MCP1633 Overview
The MCP1633 High Speed PWM Controller is a pulsewidth modulator developed for standalone power supply applications. The MCP1633 design is based on the MCP1632 PWM Controller but includes specific blocks for PWM LED dimming. It is suitable for use in topologies requiring a low side MOSFET, such as Boost, Flyback, SEPIC, CUK, etc.
