Microchip Regulated Charge Pumps

Regulated Charge Pumps

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
