DESCRIPTION
The AIC2566 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 AIC2566 draws only 22A supply current in shutdown mode. Current limit and thermal shutdown function are also provided to prevent damage. The AIC2566 is available in an 8-pin SOP exposed pad package.
* Note: C7 is needed for high ESR output capacitor
