MCP1633 Datasheet Low-side Pwm Controller

Manufacturer: Microchip Technology

Overview: MCP1633 Low-Side PWM Controller with LED Dimming Capability.

General Description

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.

Key Features

  • High Speed Current Mode Pulse-Width Modulator (PWM) Controller.
  • Easy to Interface with PIC® Microcontroller for Implementing High-Performance LED Drivers.
  • Integrated General Purpose Operational Amplifier that can be Used for Current Sensing.
  • Internal Oscillator with Adjustable Frequency via External Resistor.
  • External Synchronization Option for the Oscillator.
  • Internal Slope Compensation Circuit.
  • Current Sense to VEXT Response.
