GENERAL DESCRIPTION
The EV1529DR-00A evaluation board is
designed to drive 2 strings of up to 4 backlight
LEDs to 30mA and a 4-LED flash string to
150mA from a single Lithium-Ion battery. The
board is set up to obtain 20mA backlight
current, 40mA preview current and 100mA flash
current. All the LED currents can be adjusted by
resistors RS1, RS2, and RS3 on the evaluation
board.
The MP1529 switches at 1.2MHz and allows
the use of tiny, low cost capacitors and small
inductors. High frequency PWM dimming is
made possible through EN1. The MP1529
includes
built-in
open-LED
protection, cycle-by-cycle current limit, over-
temperature shutdown, input under-voltage
control and integrated soft-start.
