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