LM27342 Datasheet 2 Mhz 1.5a/2a Wide Input Range Step-down DC-dc Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM27341/LM27342 2 MHz 1.5/2A Wide Input Range Step-Down DC-DC Regulator with Frequency Synchronization .. December 16, 2008 LM27341/LM27342 2 MHz 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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 ponents the LM27341 and LM27342 are easy to use.

Key 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.
