Microchip MCP1630 & MCP19114

High-Speed, Microcontroller-Adaptable, Pulse Width Modulator

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

Typical applications include:

  • Smart battery chargers
  • Intelligent power systems
  • Brick DC/DC converters
  • AC power-factor correction
  • Multiple output power supplies
  • Multi-phase power supplies

The MCP1630/V inputs were developed to be easily attached to the I/O of a MCU. The MCU supplies the oscillator and reference to the MCP1630/V to provide the most flexible and adaptable power system. The power system switching frequency and maximum duty cycle are set using the I/O of the MCU. The reference input can be external, a D/A Converter (DAC) output or as simple as an I/O output from the MCU. This enables the power system to adapt to many external signals and variables in order to optimize performance and facilitate calibration.

When operating in Current mode, a precise limit is set on the peak current. With the fast comparator speed (typically 12 ns), the MCP1630 is capable of providing a tight limit on the maximum switch current over a wide input voltage range when compared to other high-speed PWM controllers.

For Voltage mode or Average Current mode applications, the MCP1630V provides a larger range for the external ramp voltage.

Additional protection features include:

  • UVLO
  • Overtemperature
  • Overcurrent


Digitally Enhanced Power Analog Current Controller

The Microchip MCP19114 is a mid-voltage (4.5-42V) analog-based PWM controller with an integrated 8-bit PIC™ Microcontroller. This unique product family combines the performance of a high-speed analog solution, including high-efficiency and fast transient response, with the configurability and communication interface of a digital solution. Combining these solution types creates a new family of devices that maximizes the strengths of each technology to create a more cost-effective, configurable, high-performance power conversion solution.

The MCP19114 - a smaller, functionally equivalent version of our MCP19115 - includes both hardware and software tools, provide a convenient and powerful development platform upon which to develop and evaluate your Boost and Buck/Boost power supply design.
