38V SYNCHRONOUS BUCK

CONVERTER



DESCRIPTION

The UTC UD38251 is a monolithic synchronous buck regulator.

The device integrates two internal power MOSFETs, and provides

2.5A of continuous load current over a wide input voltage of 8V to

38V. Current mode control provides fast transient response and

cycle-by-cycle current limit.

An internal soft-start prevents inrush current at turn-on, provides

a very compact solution with minimal external components.



FEATURES

* Wide 8V to 38V Operating Input Range

* Integrated 140mΩ Power MOSFET Switches

* Output Adjustable from VFB(1.00V±2%) to 20V

* Up to 93% Efficiency

* Internal Soft-Start

* Stable with Low ESR Ceramic Output Capacitors

* Fixed 160KHz Frequency

* Cycle-by-Cycle Over Current Protection

* Input Under/Over Voltage Lockout
