ZA3020 Mar. 2002 V Viim miiccrroo C Coorrp poorraattiioon n General Description The ZA3020 is a monolithic step-down (buck) regulator 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. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode the regulator draws less than 20uA current. The ZA3020 requires a minimum number of readily available standard external components. A synchronization pin allows the part to be driven to 600KHz. Features
