EVALUATION BOARD

General Description

Absolute Maximum Ratings

-0.5V to 28V

The EV0056 evaluation board is designed for

backlights using white LEDs. It implements

MPS’ MP1518 fixed frequency step-up

converter.

All Other Pins except OV

-0.3V to 6.5V

Recommended Operating Conditions

IN Supply Voltage

2.5V to 6V

The MP1518 is a 6 pin thin SOT23 step up

converter designed for driving up to 6 series

white LEDs from a single cell Lithium Ion

battery. The MP1518 uses current mode, fixed

frequency architecture to regulate the LED

current, which is measured through an external

current sense resistor. It’s low 100mV

feedback voltage reduces power loss and

improves efficiency. To prevent damage due

to an open circuit condition, the OV pin

monitors the output voltage and turns off the

converter if an over-voltage condition is

present.

Features

ꢀ

On Board Power MOSFET

Drives up to 6 Series White LEDs

Up to 86% Efficiency

Over 1MHz Fixed Switching Frequency

Open Load Shutdown

Low 100mV Feedback Voltage

Soft Start/PWM Dimming

UVLO, Thermal Shutdown

Internal Current Limit

Applications

The MP1518 includes under-voltage lockout,

current limiting and thermal overload protection

preventing damage in the event of an output

overload. The MP1518 is available in a small 6

lead TSOT23 package.
