Onboard high output current drive capability without external MOSFET drivers. Flexibility Ability work with wide line voltage range. Different levels under-voltage lockout thresholds self bias auxiliary bias applications. Ability synchronize controllers eliminate noise issues. Power Level requirements applicable power supplies above Higher power converters require ZCT/ZVT techniques achieve high efficiencies. Some simpler control techniques usable high power levels.
Design Factors
Control Method Average Current Mode (ACM) Optimum control method achieve harmonic distortion. Transition Mode Simpler inexpensive control with high peak currents filtering requirements. Mode type soft switching technique, which reduces allows higher frequency operations. Protection Soft-start (programmable) provides controlled start-up. Over-current protection (OCP) provides protection during overload conditions. Over-voltage protection (OVP) prevents output capacitor, switches load from overcharge condition.

Design Factors
Current Sensing power supply output current sensed either high side output being loadshared. controllers (UC3907, UCC39002) used either arrangement; however, UC3902 dedicated low-side (ground referenced) current sensing. Single Differential Current Sensing Optimal results obtained using differential current-sense technique both high- low-side applications. singleended configuration reduces count dedicated, ground-referenced applications. Single Differential Share Depending amount noise specific application, designers choose either single-ended differential type common loadshare command among modules being shared. True differential mode offers most noise immunity, singleended variety also yield excellent results when designed with high amplitude loadshare signal. Master/Slave Status loadshare controller (the UC3907) features master/ slave output signal interfacing with other power supplies end-system diagnostic circuits. Hot-Swap/Hot-Plug UCC39002 features ability hot-swap hot-plug modular power supplies without disturbing loadshare "share" command. Current Loop Compensation Each these loadshare controllers offers designers ability compensate current share loop required system individual power supplies.

Design Factors
Plug-in power solutions board-mounted, completely integrated, DC/DC converters requiring only external components. Input Voltage (VIN) Plug-in power solutions designed work from industrystandard voltages. Output Current (IOUT) IOUT converter should match maximum current need your application. Output Voltage (VOUT) Choose adjustable fixed VOUT that meets your requirements. Isolation Converters with electrical input output isolation usually more complex more expensive. Features TurboTrans,SmartSync, adjustable VOUT, remote sense, over-temperature, over-current output inhibit some many features. Airflow Requirements current converters often depends airflow. curves determine airflow needs converters specific currents. Protection Fault protection include short circuit, over-temperature, over-current over-voltage protection. Package Vertical mounting uses smallest footprint. Surface mount horizontal through-hole available most product series.

Linear Dropout (LDO) Regulators
Thermal Management," support. higher power dissipation requirements higher efficiency, recommends step-down (buck) DC/DC converters/controllers (refer pages 28-34 products). Capacitor Requirements output capacitor especially critical stability. Therefore, some LDOs require tantalum output capacitors, which have high ESR. stable with output capacitor with low-ESR ceramic output capacitors, usually stable with types capacitors. Audio Other Noise-Sensitive Applications Select with high power supply ripple rejection (PSRR) noise immunity from input supply, output noise µVrms). Some LDOs have bypass (BP) adding capacitance lower output noise. PG/SVS Devices such microprocessors, DSPs FPGAs require minimum voltage proper operation. supply voltage supervisor (SVS) function monitors system voltages outputs signal when voltages drop below certain value, system reset prevent malfunction. asserts reset signal after specified delay, while power-good (PG) function does have delay. Reverse Leakage Protection special applications where voltage output higher than input, reverse leakage protection feature prevents current from flowing from output input, which damaging input supply, especially battery.

Choose most suitable voltage that handle current needed system. Output Voltage output voltage adjusted down controller reference voltage using voltage divider. Output Current Output current often external power MOSFETs. Paralleling multiple power MOSFETs control higher currents, long MOSFET drivers adequately drive external FETs. Efficiency Higher efficiency will help with thermal issues, since wasted power converted into heat. Higher currents quickly generate more heat, airflow board space must considered. Accuracy Today's advanced processors need better accuracy support lower core voltages. There cost tradeoff when more accurate controller needed.

Design Factors
Efficiency Solution Size inductive switching converters with integrated switches recommended when highest conversion efficiency smallest solution size desired. TI's family low-power DC/DC converters (TPS6xxxx) SWIFT(TPS54xxx) point-ofload step-down DC/DC converters achieve peak efficiencies. Synchronous rectification only replaces cost external Schottky rectifier diode also increases converter efficiency 10%. Higher efficiency will directly translate into additional operating time battery-powered applications smaller power dissipation highcurrent applications, easing thermal design. Integrating high- low-side switching FETs reduces board space, only resistors capacitors along with inductor required externally operation. Depending output current, DC/DC converters
come packages such (800 mA), SOT-23 (400 mA), QFN-10 (1.2 TSSOP28 further reducing solution size. Output Current Output current typically limited size integrated FETs rated minimum input voltage (endof-discharge voltage battery systems) TPS6xxxx series. TPS54xxx output current denotes continuously available output current; higher peak-currents achievable ensure proper supply start-up high-performance DSP, FPGA ASIC systems. Boost converters, datasheet specifies current limit built-in switches. rough estimate output current obtained using formula: IOUT 0.65 ISwitch(min) (VIN/VOUT) output currents below efficiencies under 90%, inductorless charge-pump DC/DC regulators cost spaceefficient alternative (see pages 35-36).
Input Voltage DC/DC converters operate from wide range input sources: power modules, wall supplies batteries. TPS6xxxx series with small packaging quiescent current optimized low-power, battery-operated applications. batterypowered systems input voltage changes over wide range while battery being discharged. this reason converter selection depends given battery technology number cells. TPS54xxx SWIFTseries operate from preregulated 24-, 12-, 3.3-V voltages. Output Voltage Lower voltages required today's advanced DSPs, FPGAs ASICs. allow maximum flexibility, both fixed adjustable output voltages down available. TPS61xxx allows input voltage step-up high

Design Factors
Efficiency Solution Size charge pumps recommended when tradeoff between efficiency solution size needs made. Higher efficiency will directly translate into additional operating time battery-powered applications. Charge pumps achieve peak efficiencies typically require only capacitors operation. inductors, diodes FETs needed. Charge pumps come small packages such SOT-23 MSOP-8, which further reduce solution size. Output Current Charge pump converters allow small, power-efficient costeffective DC/DC solutions with output currents less than output voltage less than larger output currents, higher output voltages greater efficiency required, inductive switching converter more cost- space-efficient (pages 28-34).
Output Ripple Noise charge pumps reduce output voltage ripple minimum operating pair integrated charge pump loops with phase shift degrees. This helps avoid cost additional filtering output. Charge pumps also tend generate less noise than equivalent inductive switching converter equal output current rating. This important RFsensitive low-noise applications.

Capacitors rated photoflash applications will have short lifespan this application. IGBT Look photoflash rating when selecting IGBT used trigger flash tube. There several IGBTs that withstand voltage surge currents associated with flash; however, they usually come very large package since these ratings continuous duty. photoflashrated IGBT same ratings comes small package since loads surge continuous.
