FAN48630 — 2.5 MHz, 1500 mA, Synchronous TinyBoost^™

Regulator with Bypass Mode

Features

Description

The FAN48630 allows systems to take advantage of new

battery chemistries that can supply significant energy when

the battery voltage is lower than the required voltage for

system power ICs. By combining built-in power transistors,

synchronous rectification, and low supply current; this IC

provides a compact solution for systems using advanced

Li-Ion battery chemistries.

Few External Components: 0.47 µH Inductor and

0603 Case Size Input and Output Capacitors

Input Voltage Range: 2.35 V to 5.5 V

Fixed Output Voltage Options: 3.0 V to 5.0 V

Maximum Continuous Load Current: 1500 mA

at V_INof 2.6 V Boosting V_OUTto 3.5 V

The FAN48630 is a boost regulator designed to provide a

minimum output voltage (V_OUT(MIN)) from a single-cell Li-Ion

battery, even when the battery voltage is below system

minimum. Output voltage regulation is guaranteed to a

maximum load current of 1500 mA. Quiescent current in

Shutdown Mode is less than 3 µA, which maximizes battery

life. The regulator transitions smoothly between Bypass and

normal Boost Mode. The device can be forced into Bypass

Mode to reduce quiescent current.

Up to 96% Efficient

True Bypass Operation when V_IN> Target V_OUT
