Microchip Inverting or Doubling Charge Pumps

Inverting or Doubling Charge Pumps

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

How Can Charge Pump ICs Solve Your Design Challenges?
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
