AAT2806
Dual High Efficiency Charge Pump
for White LED and Flash Applications
General Description
The AAT2806 is a dual charge pump designed to
support both the white LED backlight and flash appli-
cations for systems operating with lithium-ion/poly-
mer batteries. The backlight charge pump is capable
of driving up to four LEDs at a total of 80mA. The cur-
rent sinks may be operated individually or in parallel
for driving higher current LEDs. To maximize power
efficiency, the charge pump operates in 1X, 1.5X, or
2X mode, where the mode of operation is automati-
cally selected by comparing the forward voltage of
each LED with the input voltage. AnalogicTech's

Cwire鈩?(Simple Serial Control鈩? serial digital
input is used to enable, disable, and set current for
each LED with an eight-level logarithmic scale plus
four low-current settings down to 50碌A(chǔ) for optimized
efficiency, with a typical operating quiescent current
of less than 50碌A(chǔ).
The flash charge pump is a charge pump doubler
with a regulated output voltage. It is designed to
deliver 120mA of continuous current and up to
250mA of pulsed current. It has an independent
enable pin for improved power savings.
The AAT2806 has thermal protection and built-in soft-
start circuitry. A low-current shutdown feature discon-
nects the load from V
IN
and reduces quiescent cur-
rent to less than 1碌A(chǔ).
The AAT2806 is available in a Pb-free, space-saving,
thermally-enhanced TDFN44-16 package and is
rated over the -40擄C to +85擄C temperature range.
