DESCRIPTION
The AIC2565 is a high efficiency, step-down DC/DC converter that builds in a high side power MOSFET. It offers continuous 3A output current over a very wide input voltage range with excellent load and line regulation.
Well-performed current mode operation makes fast transient response and feedback loop stabilization easier.
The AIC2565 draws only 22uA supply current in shutdown mode. Current limit and thermal shutdown function are also provided to prevent damage. The AIC2565 is available in SOP-8E package.
