Overview

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.

  • Input power from 2.2V to 16V
  • Output voltage adjustable down to 0.6V
  • Power Good flag, adjustable soft-start and output enable for easy power sequencing
  • Output over-voltage and under-voltage latch-off (LM2727)
  • Output over-voltage and under-voltage flag (LM2737)
  • Reference Accuracy: 1.5% (0˚C - 125˚C)
  • Current limit without sense resistor
  • Soft start
  • Switching frequency from 50 kHz to 2 MHz
  • TSSOP-14 package
