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.


