... APPLICATION INFORMATION GENERAL DESCRIPTION AIC1641 PFM (pluse frequency modulation) control- ler ICs combine a switch mode regulator, push pull driver, precision voltage reference, and voltage de- tector in a single monolithic device. They offer both extreme low quescient current, high efficiency, and very low gate threshold voltage to ensure start-up with low battery voltage ( 0 ...

... ON time. Sec- I OUT ond, the inductance must also be high enough so maximum current rating of AIC1641 and inductor are not exceed at the other worst case cindition of maximum input voltage and ON time. Lastly, the in- ductor must have sufficiently low DC resistance so excessive power is not lost as heat in the windings ...
