... LTC3525-3.3/LTC3525-5 U OPERATIO The LTC3525 is a high performance Burst Mode operation only, synchronous boost converter requiring only three small external components. Its simplicity and small size make it a high efficiency alternative to charge pump designs designed to start up from a single alkaline or nickel cell, with input voltages as low as 1V, or from two or three cells (or a Li-ion battery), with voltages as high as 4 ...

... U OPERATIO www.DataSheet4U.com load using the minimum recommended 10µF output ca- pacitor for the LTC3525-3.3 and a 22µF capacitor for the LTC3525-5 (due to the capacitor’s DC bias effect). An antiring circuit damps any oscillation at the switch node when the inductor current falls to zero. Power Adjust Feature ...

... LTC3525-3.3/LTC3525-5 U OPERATIO Component Selection Inductor values between 4.7µH and 15µH are recom- mended. In most applications 10µH will yield the best compromise between size and efficiency. The inductor should be a low-loss ferrite design and must be rated for peak currents of at least 400mA without saturating. Induc- tors with lower DC resistance will improve efficiency ...
