The MPQ24833-B from Monolithic Power Systems is an Automotive Qualified LED Driver IC that is ideal for general LED illumination, LCD backlight panels, portal GPS devices, multimedia players, and automotive lighting applications. This LED driver has an input voltage of 4.5 V to 55 V. It offers an excellent load and line regulation over a wide input supply range. This LED driver utilizes a current mode operation that provides a fast transient response and significantly simplifies the loop stabilization mechanism. It incorporates both DC and PWM dimming control mechanisms into a single control pin and uses a separate input reference ground pin to allow direct enable and/or dimming control for positive-to-negative power conversion. This AEC-Q100 Grade 1 qualified LED driver integrates open-string protection, cycle-by-cycle over-current protection (OCP), output short-circuit protection (SCP), and thermal shutdown to prevent any over-load-related damages. It is available in a surface-mount package that measures 5 x 5.80 mm.
