Product Description

The EV24830-S-00C is designed to demonstrate the capabilities of the MP24830, a 90V white LED driver that is suitable for step-down applications. It supports a wide input range with excellent load and line regulation. Its configurable current limit provides customized applications with a wide power range. Current mode operation provides fast transient response and eases loop stabilization. Protections include thermal shutdown, cycle­by­cycle over-current protection (OCP), open-string protection, and output short-circuit protection (SCP).

The MP24830 incorporates both DC and PWM dimming onto a single control pin. The separate input reference ground pin allows for direct enabling and/or dimming control for positive to negative power conversion. The MP24830 is available in a SOIC-14 package.

Partial Power Buck-Boost WLED Driver ( MP24830-C470 for Backlight, MP24830 for General Lighting )

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, cycle­by­cycle 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.
