MPQ2483ADQ
DESCRIPTION
The MPQ2483A is a 55V LED driver suitable for either step-down or inverting step-up and stepdown applications. It achieves a 2.5A peak current with excellent load and line regulation over a wide input supply range.
The MPQ2483A incorporates both DC and PWM dimming into a single control pin. The separate input reference ground allows for direct enable and dimming control for positiveto-negative power conversion.
Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include cycle-by-cycle peak current limiting, output over-voltage protection (OVP), open-string protection, output short-circuit protection (SCP), and thermal shutdown.
The MPQ2483A requires a minimal number of readily available, standard, external ponents and is available in 10-pin QFN (3mmx3mm) and 14-pin SOIC14 packages.
