MPQ24833-B LED Drivers Monolithic Power Systems (MPS) MPQ24833-B LED Drivers are 55V, 3A LED lighting drivers suitable for step-down, inverting step-up/step-down, and step-up applications. These drivers achieve 3A of output current with excellent load and line regulation over a wide input supply range. The current mode operation provides a fast transient response and eases loop stabilization. The MPQ24833-B LED drivers feature thermal shutdown, analog and PWM dimming, cycle-by-cycle peak current limiting, open-string protection, and output Short-Circuit Protection (SCP). Typical applications include general LED illumination, LCD backlight panels, automotive lighting, portable multimedia players, and portable GPS devices.
