LM2727, LM2737 .ti. SNVS205D - AUGUST 2002 - REVISED MARCH 2013 LM2727/LM2737 N-Channel FET Synchronous Buck Regulator Controller for Low Output Voltages Check for Samples: LM2727, LM2737 Features - 2 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 k Hz to 2 MHz - TSSOP-14 Package APPLICATIONS - Cable Modems - Set-Top Boxes/ Home Gateways - DDR Core Power - High-Efficiency Distributed Power - Local Regulation of Core Power 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 under-voltage latchoff. 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...
