| 38V SYNCHRONOUS BUCK CONVERTER WITH CC/CV
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.
