ACT4065 Datasheet | Microelectronic

A, 450 KHz Step-Down Converter DESCRIPTION The ACT4065 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation. The ACT4065 requires a minimum number of readily available standard external ponents. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-bycycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25µA of supply current. Features z z z z z z z z z z 2A Output Current 0.22Ω Internal Power MOSFET Switch Stable with Low ESR...
