Synchronous
Regulator, TINYBOOST), 3 MHz
FAN4860
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 combination of built−in power
transistors, synchronous rectification, and low supply current make the FA...
