LM27342 - 2 MHz 1.5A/2A Wide Input Range Step-Down DC-DC Regulator

This page provides the datasheet information for the LM27342, a member of the LM27341 2 MHz 1.5A/2A Wide Input Range Step-Down DC-DC Regulator family.

Datasheet Summary

Description

The LM27341 and LM27342 regulators are monolithic, high frequency, PWM step-down DC-DC converters in 10-pin LLP and 10-pin eMSOP packages.

They contain all the active functions to provide local DC-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.

Features

  • include internal soft-start circuitry to reduce inrush current, pulse-by-pulse current limit, thermal shutdown, and output over-voltage protection. Features.
  • Space saving 3 X 3 mm LLP-10 & eMSOP-10 package Wide input voltage range 3 to 20 V Wide output voltage range 1 to 18 V LM27341 delivers 1.5A maximum output current LM27342 delivers 2A maximum output current High switching frequency 2 MHz Frequency synchronization 1.00 M.

LM27341/LM27342 2 MHz 1.5/2A Wide Input Range Step-Down DC-DC Regulator with Frequency Synchronization www.DataSheet4U.com December 16, 2008 LM27341/LM27342 2 MHz 1.5A/2A Wide Input Range Step-Down DC-DC Regulator with Frequency Synchronization General Description The LM27341 and LM27342 regulators are monolithic, high frequency, PWM step-down DC-DC converters in 10-pin LLP and 10-pin eMSOP packages. They contain all the active functions to provide local DC-DC conversion with fast transient response and accurate regulation in the smallest possible PCB area. With a minimum of external components the LM27341 and LM27342 are easy to use. The ability to drive 1.5A or 2A loads respectively, with an internal 150 mΩ NMOS switch results in the best power density available.
