UCC36451
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
* Integrated 75mΩ high side Power MOSFET Switches
* Output Adjustable: V_FB (1.00V±2%).
* 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
