UCC40501 - SYNCHRONOUS BUCK CONVERTER

General Description

The UTC UCC40501 is a monolithic synchronous buck regulator.

The device integrates internal high side and external low side power MOSFETs, and provides 5A of continuous load current over a wide input voltage.

Current mode control provides fast transient response and cycle-by-cycle current limit.

UNISONIC TECHNOLOGIES CO., LTD UCC40501 40V, 5A SYNCHRONOUS BUCK CONVERTER WITH 2CH CC/CV CMOS IC  DESCRIPTION The UTC UCC40501 is a monolithic synchronous buck regulator. The device integrates internal high side and external low side power MOSFETs, and provides 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.  FEATURES * Wide 8V to 40V Operating Input Range * Integrated 45mΩ high side Power MOSFET Switches * Output Adjustable from VFB (1.
