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 bi...
