TPS53313RGET

TEXAS INSTRUMENTS  TPS53313RGET  直流-直流开关降压逐步递减稳压器, 可调, 4.5V-16V输入, 600mV-11.2V输出, 6A输出, QFN-24

The is a synchronous Buck Converter integrates two N-channel MOSFETs. Due to low RDSon and proprietary SmoothPWM™ skip mode of operation, it optimizes the efficiency at light-load condition without compromising the output voltage ripple. The TPS53313 features programmable from 250kHz to 1.5MHz switching frequency with selectable skip mode or forced CCM mode operation. The device provides pre-biased startup, soft-stop, integrated bootstrap switch, power good function and EN/input UVLO protection. It supports input voltage from 4.5 to 16V and no extra bias voltage is needed. The output voltage is adjustable from 0.6V up to 0.7 x VIN.
