HIGH VOLTAGE SYNCHRONOUS PWM BUCK CONTROLLER
Description
The IR3651 is a high voltage PWM controller
designed for high performance synchronous Buck
DC/DC applications. The IR3651 drives a pair of
external N-MOSFETs using a programmable
switching frequency up to 400kHz allows flexibility
to tune the operation of the IC to meet system
level requirements, and synchronization allows
the simplification of system level filter design. The
output voltage can be precisely regulated using
the internal 1.25V reference voltage for low
voltage applications. Protection such as under
voltage lockout and hiccup current limit are
provided to give required system level security in
the event of fault conditions.
