A, 450 KHz Step-Down Converter
ACT4065
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 components.
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.
