DESCRIPTION
The EV1527DR-02A evaluation board is
designed to drive a single Lumileds LED with
low, forward voltage for Camera Flash
applications. The board is set up to obtain
150mA torch current and 750mA flash current
with an input voltage range of 3.0V to 4.2V. The
torch and flash currents can be adjusted by
resistors R2 and R3 on the Evaluation Board.
The MP1527 switches at 1.3MHz and allows
the use of tiny, low cost capacitors and small
inductors. External compensation and soft-start
result in small inrush current and extend the
battery life. The MP1527 operates from an input
voltage as low as 2.6V.
