APPLICATION INFORMATION Operation
TPS6205x synchronous step-down converter that operates with 850-kHz fixed frequency pulse width modulation (PWM) moderate heavy load currents enters power-save mode light load current. During operation converter uses unique fast response voltage mode control scheme with input voltage feed forward achieve good line load regulation with small ceramic input output capacitors. beginning each clock cycle initiated clock signal (S), P-channel MOSFET switch turned inductor current ramps until voltage-comparator trips control logic turns switch off. Also switch turned current limit comparator case current limit P-channel switch exceeded. After dead time preventing current shoot through, N-channel MOSFET rectifier turned inductor current ramps down. next cycle initiated clock signal again, turning N-channel rectifier turning P-channel switch. error amplifier well input voltage determines rise time tooth generator; therefore, change input voltage output voltage directly controls duty cycle converter giving very good line load transient regulation.
Constant Frequency Mode Operation (SYNC HIGH)
constant frequency mode, output voltage regulated varying duty cycle signal range 100% 10%. Connecting SYNC voltage greater than forces converter operate permanently mode even light load currents. advantage converter operates with fixed switching frequency that allows simple filtering switching frequency noise sensitive applications. this mode, efficiency lower compared power-save mode during light loads (see Figure 16). N-MOSFET devices stays even when current into output drops zero. This prevents device from going into discontinuous mode. device transfers unused energy back input. Therefore, there ringing output that usually occurs discontinuous mode. duty cycle range constant frequency mode 100% 10%. possible switch from forced mode power-save mode during operation pulling SYNC low. flexible configuration SYNC during operation device allows efficient power management adjusting operation TPS6205x specific system requirements.
Power-Save Mode Operation (SYNC LOW)
load current decreases, converter enters power-save mode operation. During power-save mode converter operates with reduced switching frequency with minimum quiescent current maintain high efficiency. Whenever average output current goes below skip threshold, converter enters power-save mode. average current depends input voltage. input voltages with maximum input voltage. average output current must below threshold least clock cycles (tcy) enter power-save mode. During power-save mode output voltage monitored with comparator. When output voltage falls below comp threshold 0.8% above nominal, P-channel switch turns P-channel switch turns peak switch current typically reached. N-channel rectifier turns inductor current ramps down. inductor current approaches zero, N-channel rectifier turned switch turned starting next pulse. When output voltage reached with single pulse, device continues switch with normal operating frequency, until comparator detects output voltage 1.6% above nominal output voltage. converter wakes again when output voltage falls below comp threshold. This control method reduces quiescent current typically switching frequency minimum achieving highest converter efficiency. Having these skip current thresholds 0.8% 1.6% above nominal output voltage gives lower absolute voltage drop during load transient anticipated with standard converter operating this mode.

APPLICATION INFORMATION (continued) Undervoltage Lockout
undervoltage lockout circuit prevents device from misoperation input voltages. prevents converter from turning switch rectifier MOSFET under undefined conditions.
Synchronization
clock signal applied, converter operates with typical switching frequency kHz. possible synchronize converter external clock within frequency range from 1200 kHz. device automatically detects rising edge first clock synchronizes external clock. clock signal stopped, converter automatically switches back internal clock continues operation. switchover initiated rising edge SYNC detected duration four clock cycles. Therefore, maximum delay time internal clock minimum frequency kHz. During this time, there clock signal available. device stops switching until internal circuitry switched internal clock source. When device switched between internal synchronization external synchronization during operation, output voltage show transient over/undershoot during switchover. voltage transients minimized using initial external frequency, changing frequency slowly value desired. voltage drop output when device switched from external synchronization internal synchronization reduced increasing output capacitor value. device synchronized external clock, power-save mode disabled device stays forced mode. Connecting SYNC enables power-save mode. converter operates mode moderate heavy loads mode during light loads maintaining high efficiency over wide load current range.
