TYPICAL APPLICATIONS CIRCUIT
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
The AIC2565 draws only 22A supply current in
shutdown mode. Current limit and thermal
shutdown function are also provided to prevent
damage. The AIC2565 is available in an 8-pin
SOP exposed pad package.
