UD05205中文资料2.0A 1.5MHZ SYNCHRONOUS BUCK CONVERTER数据手册UTC规格书

描述 Description

The UTC UD05205 is a monolithic synchronous buck regulator with a built in internal power MOSFET. It achieves 2A continuous output current fix switching frequency with excellent load and line regulation. Current mode operation provides  fast transient response and eases of loop stabilization. Fault condition protection includes cycle-by-cycle current limiting, output short circuit protection and  thermal shutdown. In shutdown mode the regulator draws less than 1μA of supply current. Internal soft-start minimizes the inrush supply current at initial startup.
