FAN4868

3 MHz, Synchronous

TinyBoost⁾Regulator

Description

The FAN4868 is a low−power boost regulator designed to provide a

regulated 3.3 V output from a single cell Lithium or Li−Ion battery.

Output voltage options are fixed at 3.3 V with a guaranteed maximum

SCALE 4:1

load current of 200 mA at V = 2.3 V and 300 mA at V = 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 FAN4868 ideal for

battery powered applications.

WLCSP6 0.88 x 1.23 x 0.458

CASE 567VM

The FAN4868 is available in 6−bump 0.4 mm pitch Wafer−Level

Chip Scale Package (WLCSP).
