Product Description

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

IC Details

The MP24830 is a 90V white LED driver suitable for either step-down or 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 a wide power range. Current mode operation provides a fast transient response and eases loop stabilization. Fault condition protection includes thermal shutdown, cycle?y?ycle peak-current limiting, open-string 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.? The MP24830 requires a minimal number of readily-available external components. It is available in 14-pin SOIC and QFN packages.
