MPQ2483A - 2.5A Programmable Frequency LED Driver

General 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.

Key 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 components and is available in 10-pin QFN (3mmx3mm) and 14-pin SOIC14 packages.

The Future of Analog IC Technology 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.
