Description

The MCP1630/V is a high-speed Pulse Width Modula-

tor (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, switch-

ing 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 and more.

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
