36V 4.5A SYNCHRONOUS BUCK CONVERTER WITH 2CH CC/CV
DESCRIPTION
The UTC UCC36451 is a monolithic synchronous buck
regulator. The device integrates internal high side and external low
side power MOSFETs, and provides 4.5A of continuous load
current over a wide input voltage. Current mode control provides
fast transient response and cycle-by-cycle current limit.
An internal soft-start prevents inrush current at turn-on, and
provides a very compact solution with minimal external
components.
FEATURES
* Wide 8V~36V Operating Input Range
