MCP1633 PWM Controllers with Dimming

Microchip Technology MCP1633 PWM (Pulse Width Modulation) Controller with Dimming is a fixed frequency current mode controller and can be used as a standalone LED driver. This controller employs the current mode for the non-V and the voltage mode for the V version. The MCP1633 controller has an integrated overvoltage comparator, low-side MOSFET driver, and battery current and battery voltage amplifiers. This controller offers internal over-temperature protection and under-voltage lockout protection.
