FAN48632

2.5 MHz, 2.0 A Pulsed-Load Synchronous TinyBoost™

Regulator with Bypass Mode for GSM PA Supply

Features

Description

Few External Components: 0.47 µH Inductor and

The FAN48632 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.

0603 Case Size Input and Output Capacitors

Input Voltage Range: 2.35 V to 5.5 V

Fixed Output Voltage : 3.3 V, 3.5 V

Maximum Continuous Load Current of: 1.5 A

at V_INof 2.6 V

The FAN48632 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. In boost mode, output voltage regulation is

guaranteed to a maximum load current of 1.5 A continuous

and 2.0 A pulsed. 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.

Maximum Pulsed Load current :of 2.0 A for GSM 217 Hz

repetition rate ,boosting V_OUTto 3.3 V or 3.5 V

Up to 96% Efficient

True Bypass Operation when V_IN> Target V_OUT
