DESCRIPTION

UTC UCC36351 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  UCC36351 provides up to 3.5A 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.
