Description
The MCP1630 is a high-speed Pulse Width Modulator (PWM) used to develop intelligent power systems. When used with a microcontroller, the MCP1630 will control the power system duty cycle to provide output voltage or current regulation. The microcontroller can be used to adjust output voltage or current, switching frequency, maximum duty cycle and other features making the power system more intelligent and adaptable.
