EV0022 (MP1522)

Precision 6 White LED Driver

Evaluation Board

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The EV0022 evaluation board uses the

MP1522 to drive up to six (6) series white LEDs

from a single cell Lithium Ion battery. The

MP1522 uses a current limited, variable

frequency architecture to regulate the LED

current, which is measured through an external

current sense resistor. Its 1.23V, 3% feedback

threshold improves the LED current regulation.

The BIAS pin can measure the output voltage

and turn off the converter to prevent damage in

an open circuit condition.

•

Internal 0.5Ω Power Switch

Output Voltage up to 25V

Up to 90% Efficiency

Low 1µA Shutdown Current

Input Under-Voltage Protection

Thermal Shutdown

Internal Current Limit

APPLICATIONS

•

Handheld Computers, PDAs

Cell Phones

Digital Still and Video Cameras

Small LCD Displays

The MP1522 includes under-voltage lockout,

current limiting and thermal overload protection

preventing damage in the event of an output

overload. The MP1522 is available in tiny 5-pin

SOT23 packages.
