DESCRIPTION

The EV2487DN-00A is an evaluation board for the

MP2487DN, a step down converter designed for

driving up to 10 white LEDs in series with 330mA

current.

The MP2487 is a peak current mode control, fixed

frequency regulator to deliver a constant current

of up to 1A 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 MP2487 is available in a SOIC8E package.
