AAT3192/93
Low-Cost, 2-/3-Channel
Charge-Pump LED Drivers
3193.2007.05.1.0

ChargePump
General Description
The AAT3192 and AAT3193 are charge-pump
based, current-sink white LED drivers capable of
driving one to three LEDs up to 30mA, each. They
automatically switch between 1x mode and 2x
mode to maintain the highest efficiency and opti-
mal LED current accuracy and matching.
The AAT3192/93 charge pump’s 1x mode (bypass
mode) has very low resistance allowing LED cur-
rent regulation to be maintained with input supply
voltage approaching the LED forward voltage.
The AAT3192 and the AAT3193 are available in a
2x2mm 10-lead SC70JW-10 packages.
