Pulsed-Load Synchronous
Regulator with Bypass Mode
for GSM PA Supply,
TINYBOOST), 2.5 MHz, 2.0 A
FAN48632
Description
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.
The FAN48632 is a boost regulator designed to provide a minimum
output voltage (VOUT(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 mA, 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.
The FAN48632 is available in a 16−bump, 0.4 mm pitch,
Wafer−Level Chip−Scale Package (WLCSP).

A1
EN
Enable. When this pin is HIGH, the circuit is enabled (Note 2).
A2
PG
Power Good. This is an open−drain output. PG is actively pulled LOW if output falls out of
regulation due to overload or if thermal protection threshold is exceeded.

VIN
VSEL
AGND
Input Voltage. Connect to Li−Ion battery input power source (Note 2).
Output Voltage Select. When boost is running, this pin can be used to select output voltage.
Analog Ground. This is the signal ground reference for the IC. All voltage levels are measured
with respect to this pin.
B3–B4
C1
VOUT
BYP
Output Voltage. Place COUT as close as possible to the device.
Bypass. This pin can be used to activate Forced Bypass Mode. When this pin is LOW, the
bypass switches (Q3 and Q1) are turned on and the IC is otherwise inactive.
C3–C4
SW
Switching Node. Connect to inductor.
D2–D4
PGND
Power Ground. This is the power return for the IC. The COUT bypass capacitor should be
returned with the shortest path possible to these pins.
2. The EN pin can be tied to VIN, but it is recommended to tie EN to the 1.8 V logic voltage.
