UNISONIC TECHNOLOGIES CO., LTD 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: VFB (1.00V±2%).
