DESCRIPTION

The AIC1633 is a high efficiency step up DC/DC converter. Only four external components are required to deliver a fixed voltage of 3V, 3.3V, or 5V. The output voltage can be externally set to an arbitrary value below breakdown voltage of the power switch for AIC1633A. Efficiency beyond 83 can be easily achieved at 70mA load with 2.2V to 3V input voltages.

FEATURES

• High Efficiency Up To 87.

• Adjustable Output Voltage with Two Resistors (AIC1633A)

• Power-Saving Shutdown Mode (7µA typical).

• Internal 0.8A Switch.
