Datasheet Summary
Synchronous Regulator, TINYBOOST), 3 MHz
Description The FAN4860 is a low- power boost regulator designed to provide a regulated 3.3 V, 5.0 V or 5.4 V output from a single cell Lithium or Li- Ion battery. Output voltage options are fixed at 3.3 V, 5.0 V, or 5.4 V with a guaranteed maximum load current of 200 mA at VIN = 2.3 V and 300 mA at VIN = 3.3 V. Input current in Shutdown Mode is less than 1 μA, which maximizes battery life.
Light- load PFM operation is automatic and “glitch- free”. The regulator maintains output regulation at no- load with as low as 37 μA quiescent current.
The bination of built- in power transistors, synchronous rectification, and low supply current make the...
