HIGH FREQUENCY SYNCHRONOUS PWM BUCK CONTROLLER
WITH POWER GOOD OUTPUT
Description
The IR3629/IR3629A is a PWM controller
designed for high performance synchronous Buck
DC/DC applications. The IR3629/IR3629A drives
a pair of external N-MOSFETs using a fixed
600kHz (300kHz “A version”) 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. Protection such as Pre-Bias
startup, hiccup current limit and thermal shutdown
provide the required system level security in the
event of fault conditions.
