DC-DC Charge Pump ICs – Voltage Boosting or Voltage Inverting

View All Parametrics

Low-Cost Voltage Boosters for Low-Current Applications

Charge pump ICs are simple and low-cost solutions for boosting voltage under light load conditions in small, battery-operated and other low-power applications. Unlike boost converters, charge pump ICs can operate without inductors and other external components and require just two capacitors for energy storage. This reduces costs and saves board space in your design. Our portfolio of charge pumps includes devices that enable doubled, inverted or regulated voltage output in a variety of applications including LED lighting, automotive, industrial and more.

Benefits

  • Reduce costs: cost-effective alternative to conventional boost converter (switching regulator)
  • Simplify development: easy-to-implement solutions for low-current applications
  • Save board space: no need for inductors or external Field Effect Transistors (FETs)
  • Speed up time to market: excellent options for reducing development time for battery-powered applications

Features

  • Highly efficient for low-output currents
  • Regulated, inverted or doubled output voltage options available
  • Wide input voltage up to 18V
  • Selectable output of 3.3V or 5.0V on regulated charge pumps
  • Adjustable output from 1.5V to 5.5V on regulated charge pumps
