MCP1632 - Microchip

MCP1632 Low-Side PWM Controller

The MCP1632 high-speed PWM controller is a pulse-width modulator developed for stand-alone power supply applications. The MCP1632 includes a high-speed analog control loop, a logic-level MOSFET driver, an internal oscillator, a reference voltage generator, and internal slope compensation. This high level of integration makes it an ideal solution for standal.
