AIC1631 General 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 exter-nally set to an arbitrary value below breakdown voltage of the power switch for AIC1631A. Effi-ciency beyond 87% can be easily achieved at 100mA load with 2.2V to 3V input voltages.

Logic-controlled shutdown mode is provided for power saving. Switch current limit can be pro-grammed with a resistor. The low battery detec-tor can be configured as a linear regulator or a burst mode controller performing an extremely low supply current operation.

120KHz switching rate reduces the inductor size. Inductors of 25uH to 50uH inductance are recommended for most applications.
