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.
