MPQ2483DS
DESCRIPTION
The MPQ2483 is a 55V, LED driver suitable for either step-down or inverting step-up/down applications. It achieves 2.5A peak current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes thermal shutdown, cycle-by-cycle peak current limiting, output over voltage protection, open strings protection and output short circuit protection.
The MPQ2483 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 MPQ2483 requires a minimum number of readily available standard external ponents and is available in a 10-pin 3mm x 3mm QFN and SOIC 14-pin packages.
