DESCRIPTION

The AIC1631 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 AIC1631A. Efficiency beyond 87 can be easily achieved at 100mA load with 2.2V to 3V input voltages.
