Privacy Policy

We offer a rapidly-expanding portfolio of DC-DC controller products to serve the mobile device, portable computer, telecommunications and industrial markets. Our Constant On-Time (COT), Pulse-Width Modulated (PWM) and Digitally Enhanced Power Analog (DEPA) controllers are best-in-class products that are designed to provide high efficiency in a small form factor.

Pulse-Width Modulated (PWM) and Constant On-Time (COT) Controllers

These devices offer voltage and current mode control options to regulate boost, buck, flyback and a variety of other topologies.

Digitally Enhanced Power Analog (DEPA)

These analog-based PWM controllers integrate an 8-bit PIC® microcontroller. This unique product offering combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution.

Design Resources

MPLAB® Analog Designer

Provides design suggestions for common circuit needs, estimates performance for common modifications, and can export to MPLAB® Mindi™ Analog Simulator for verification.

MPLAB® Mindi™ Analog Simulator

Uses a SIMetrix / SIMPLIS environment to model circuit behavior, reducing design time with software debugging for initial design verification.

Power Check Design Service

Provides advice on your exact physical circuit layout, sharing best practices from an experienced power supply designer, so that physical hardware will match simulations.
