DESCRIPTION
The EV1519DQL-00A is an evaluation board for
the MP1519, a fully automatic driver for
powering three 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.
