Description

The ZA3020 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.

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 23A of supply current.

The ZA3020 requires a minimum number of readily available standard external components. A synchronization pin allows the part to be driven to 600KHz.
