MPQ24833-B is a 55V, 3A, LED driver suitable for step-down, inverting step-up/step-down and step-up applications. The MPQ24833-B achieves 3A of output current with excellent load and line regulation over a wide input supply range. Current mode operation provides a fast transient response and eases loop stabilization. Full protection features include thermal shutdown, cycle by cycle peak current limiting, open-string protection, and output short-circuit protection (SCP). It incorporates both DC and PWM dimming into 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 MPQ24833-B requires a minimal number of readily available, standard external components and is available in an SOIC-8 EP package. Typical applications include general LED Illumination, LCD backlight panels, automotive lighting, portable multimedia players and portable GPS devices.
