Description
The MCP1630 is a high-speed Pulse Width Modulator
(PWM) used to develop intelligent power systems.
When used with a microcontroller, the MCP1630 will
control the power system duty cycle to provide output
voltage or current regulation. The microcontroller can
be used to adjust output voltage or current, switching
frequency, maximum duty cycle and other features
making the power system more intelligent and
adaptable.
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 inputs were developed to be easily
attached to the I/O of a microcontroller. The microcon-
troller supplies the oscillator and reference to the
MCP1630 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
microcontroller. The reference input can be external, a
D/A converter output or as simple as an I/O output from
the microcontroller. 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 (typi-
cally 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.
Additional protection features include: undervoltage
lockout, overtemperature and overcurrent.
