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.
