 ^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 22A 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
