38V SYNCHRONOUS BUCK

CONVERTER WITH CC/CV



DESCRIPTION

UTC UD38252 is a wide input voltage, high efficiency Active CC

step-down DC/DC converter that operates in either CV (Constant

Output Voltage) mode or CC (Constant Output Current) mode.

UTC UD38252 provides up to 2.5A output current at 160kHz

switching frequency. 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.


