TYPICAL APPLICATION CIRCUIT
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 de-
tector 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 25µH to 50µH inductance are re-
commended for most applications.
