DESCRIPTION

FEATURES

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.

3V to 4.2V Input Voltage Range

Tiny Capacitors and Inductors Due to

1.3MHz Fixed Switching Frequency

Output LED Currents: 150mA at Torch

Mode, 750mA at Flash Mode

Surface-Mount Components

Fully Assembled and Tested

APPLICATIONS

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.
