40V, 5A SYNCHRONOUS BUCK CONVERTER WITH 2CH CC/CV

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 (1.00V±2%) to 16V

* Up to 95% Efficiency

* Internal Soft-Start and Fixed 160KHz Frequency

* Stable with Low ESR Ceramic Output Capacitors

* Cycle-by-Cycle Over Current Protection

* Input Under/Over Voltage Lockout
