MAX1742 Overview

Key Specifications

Package: QSOP
Mount Type: Surface Mount
Pins: 16
Operating Voltage: 5.5 V

Description

The MAX1742/MAX1842 constant-off-time, pulse-widthmodulated (PWM) step-down DC-DC converters are ideal for use in 5V and 3.3V to low-voltage conversion necessary in notebook and subnotebook computers. These devices feature internal synchronous rectification for high efficiency and reduced component count.

Key Features

  • internal synchronous rectification for high efficiency and reduced component count
  • They require no external Schottky diode
  • The internal 90mΩ PMOS power switch and 70mΩ NMOS synchronous-rectifier switch easily deliver continuous load currents up to 1A
  • The MAX1742/MAX1842 produce a preset 2.5V, 1.8V, or 1.5V output voltage or an adjustable output from 1.1V to VIN
  • They achieve efficiencies as high as 95%
