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.
