Overview

MHX4004-MS is a low-noise, 400KHz charge pump DC/DC converter that delivers a regulated 5V output over an input voltage range of 2.7V to 5V, with excellent line and load regulation. The device maintains a stable switching frequency with a maximum output current of 300mA. It supports both PFM and PWM modes to optimize quiescent current consumption, extending battery life in portable applications — particularly suited for lithium battery-powered designs. The optimized charge pump architecture features low output ripple and minimal interference to wireless devices such as FM receivers. The IC integrates over-temperature protection, over-current protection, and soft-start functionality, with a shutdown current of less than 1uA, available in a SOT-23-6 package.

Applications

  • Smart Bluetooth speakers
  • Lithium battery backup power
  • Smart card readers
  • LED backlight drivers
  • 3V to 5V conversion

Key features

  • Fixed 5V±2% output
  • Input voltage range: 2.7V ~ 5V
  • Output voltage range: 4.9V ~ 5.1V
  • Output current up to 300mA (VIN=3.6V)
  • Low quiescent current: 0.23mA (VIN=3.6V)
  • Low-noise fixed frequency: 400KHz (VIN=3.6V)
  • Shutdown current < 1uA
  • Overtemperature and overcurrent protection
  • Soft-start function
