The MP24830 is a 90V, white LED driver suitable for inverting step‑up/down applications. It supports a wide input range with excellent load and line regulation. Its programmable current limit provides customized applications with wide power range. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes thermal shutdown, cyclebycycle peak current limiting, open strings protection and output short circuit protection.
The MP24830 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.
