... IN OUT High Efficiency Step-Up DC/DC Converter FAX: 886-3-5772510 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 ...
