DESCRIPTION

The EV2488DN-00A is an evaluation board for the

MP2488DN, a step down converter designed for

driving up to 10 white LEDs in series with 330mA

current.

The MP2488 is a peak current mode control, fixed

frequency regulator to deliver a constant current

of up to 2A to high power white LEDs. Its low

200mV feedback voltage reduces power loss and

improves efficiency.

The wide 4.5V to 55V input range accommodates

a variety of step-down applications, making it

ideal for automotive, industry and general lighting

application.

The MP2488 is available in small 3mmX3mm 10

pin QFN and SOIC8 with exposed pad package.
