Microchip | MCP1630V-E/MS

The MCP1630V-E/MS is a high-speed Pulse Width Modulator (PWM) used to develop intelligent power systems. When used with a microcontroller unit (MCU), the MCP1630V will control the power system duty cycle to provide output voltage or current regulation.

The MCU can be used to adjust output voltage or current, switching frequency, maximum duty cycle and other features that make the power system more intelligent. Typical applications include smart battery chargers, intelligent power systems, brick dc/dc converters, ac  power-factor correction, multiple output power supplies, multi-phase power supplies and more.
