Description

The MCP1630/V is a high-speed Pulse Width Modulator (PWM) used to develop intelligent power systems. When used with a microcontroller unit (MCU), the MCP1630/V 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.
