LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltages June 2003 LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltages General Description 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 undervoltage 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...
