DESCRIPTION
The EV2481-H-00A is a Buck converter evaluation
board for the MP2481, a wide input step-down
converter designed for driving high-power white
LEDs with up to 1A capability.
The MP2481 is a 1.2A output, 36V white LED
driver suitable for either step-down or inverting
step-up/down applications. It achieves 1.2A peak
output current over a wide input supply range
with excellent load and line regulation. Current
mode operation provides fast transient response
and eases loop stabilization. Fault condition
protection includes thermal shutdown, cycle-by-
cycle peak current limiting, open LED protection
and output short circuit protection.
The MP2481 incorporates both DC and PWM
dimming onto a single control pin. The separate
input reference ground pin allows for direct
enable and/or dimming control for a positive to
negative power conversion.
The MP2481 requires a minimum number of
readily available standard external components
and is available in 8-pin MSOP8 packages.
