The Future of Analog IC Technology
DESCRIPTION
The MP3011 is a fully automatic driver for
powering two white LEDs, with up to 4V forward
voltage, from a single Li-Ion or three NiMH
cells. The driver performs all of the sensing and
control to run the LEDs at an optimum charge
pump ratio for efficiency without an expensive
inductor. The driver allows PWM operation to
support brightness control.
The tiny 3mm x 3mm QFN16 package and
small external capacitors allow for the most
compact white LED solution available.

... TM MP3011 – 1X, 1.5X, 2X AUTO-ADJUST CHARGE PUMP 2 WHITE LED DRIVER OPERATION The MP3011 is a charge pump that drives 2 LEDs from a 2.5V to 5.5V input voltage. It automatically switches between 1x, 1.5x and 2x charge pump modes to optimize efficiency while maintaining LED current regulation. Two drivers independently regulate the current through the LEDs, therefore matching LEDs are not required ...
