The IR3628 is a PWM controller designed for
high performance synchronous Buck DC/DC
applications. The IR3628 drives a pair of external
N-MOSFETs using a fixed 600kHz switching
frequency allowing the use of small external
components. The output voltage can be precisely
regulated using the internal 0.6V reference
voltage for low voltage applications. IR3628
provides an efficient solution for high-speed
bandwidth data bus which requires a particular

Protection such as Pre-Bias startup, hiccup
current limit and thermal shutdown are provided
to give required system level security in the event
of fault conditions.
