FAN48623 — 2500 mA, Synchronous TinyBoost®

Regulator with Bypass Mode

Features

Description

Maximum Continuous Load Current: 2500 mA

at V_INof 2.5 V Boosting V_OUTto 3.3 V

The FAN48623 allow s systems to take advantage of new

battery chemistries that can supply significant energy w hen

the battery voltage is low er than the required voltage for

system pow er ICs. By combining built-in pow er transistors,

synchronous rectification, and low supply current, this IC

provides a compact solution for systems using advanced Li-

Ion battery chemistries.

Maximum Pulse Load Current of 3.5 A f or GSM PA s

(1 Slot) and PMIC support simultaneously, V_IN=3.1 V,

V_OUT=3.4 V

Up to 97% Efficient

4 External Components: 2520 case 0.47 µH Inductor

and 0603 Case Size Input and Output Capacitors

The FAN48623 is a boost regulator designed to provide a

minimum output voltage from a single-cell Li-Ion battery,

even w hen the battery voltage is below system minimum.

Input Voltage Range: 2.5 V to 5.5 V

Fixed Output Voltage Options: 3.0 V to 5.0 V

True Bypass Operation w hen V_IN> Target V_OUT

Integrated Synchronous Rectifier

True Load Disconnect

The output voltage regulation is guaranteed up to

maximum load current of 2500 mA. The regulator transitions

smoothly betw een Bypass and normal Boost Mode. The

device can be forced into Bypass Mode to reduce quiescent

current.

The FAN48623 is available in a 16-bump, 0.4 mm pitch,

Wafer-Level Chip-Scale Package (WLCSP).
