FAN48630
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 builtin power transistors, synchronous rectification, and
low supply current; this IC provides a compact solution for systems
using advanced LiIon battery chemistries.
The FAN48630 is a boost regulator designed to provide a minimum
output voltage from a singlecell LiIon 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 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 FAN48630 is available in a 16bump, 0.4 mm pitch,
WaferLevel ChipScale Package (WLCSP).

Enable. When this pin is HIGH, the circuit is enabled (Note 3).
Power Good. This is an opendrain output. PG is actively pulled LOW if output falls out of
regulation due to overload or if thermal protection threshold is exceeded.
Input Voltage. Connect to LiIon battery input power source (Note 3).
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.

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.
3. Do not connect the EN pin to VIN. A logic voltage of 1.8 V should control the EN pin and enable/disable the device.
