製品説明

The MPQ2483 is a 55V, white 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, cycle­by­cycle peak current limiting, input 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 is package in SO-14.

Fault condition protection includes thermal shutdown, cycle­by­cycle 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 components and is available in a 10-pin 3x3mm QFN package.


55V, 2.5A Programmable Frequency LED Driver with AEC-Q100 Qualified

The MPQ2483A is a 55V LED driver suitable for either step-down or inverting step up and step-down 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 positive-to-negative power conversion. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include cycle­by­cycle 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 components and is available in 10-pin QFN (3mmx3mm) and 14-pin SOIC14 packages.
