LM2727 / LM2737 N沟道FET同步降压稳压器控制器的低输出 LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output

DESCRIPON

The LM2727 and LM2737 are high-speed, synchronous, switching regulator controllers. They are intended to control currents of 0.7A to 20A with up to 95% conversion efficiencies. The LM2727 employs output over-voltage and under-voltage latch- off. For applications where latch-off is not desired, the LM2737 can be used. Power up and down sequencing is achieved with the power-good flag, adjustable soft-start and output enable features. The LM2737 and LM2737 operate from a low-current 5V bias and can convert from a 2.2V to 16V power rail.
