EVQ2483-Q-00A Evaluation Kit 55V, Programmable Frequency White LED Driver Evaluation Board AEC-Q100 Qualified
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 QFN10 (3 x 3)mm.

USING MAGALPHA ROTARY MAGNETIC SENSORS IN SIDE SHAFT MODEThe previous article discussed types of magnet and their uses with MPS MagAlpha sensors in “end of shaft” mode. This article will explore the “side shaft“ mode topology. MPS MagAlpha sensors utilize an array of Hall elements in the center of the IC that sense the horizontal vector of the field from the rotating magnet. This field typically comes from a simple two-pole, diam...

CHOOSING THE RIGHT MAGNET FOR MAGALPHA SENSORSThe MPS MagAlpha family offers rotary Hall effect magnetic sensors that sense the position of a magnet as it rotates above or at the side of the sensor. Exact magnet sizes, shapes, and materials should be selected depending on application requirements and target costs. This article discusses tradeoffs, and how to choose the best magnet for an application. MPS MagAlpha sensors utilize an array o...

AN INTRODUCTION TO THE MAGALPHA MAGNETIC ANGLE SENSOR FAMILYThe ability to detect position or speed is a fundamental requirement in the control and monitoring of many mechanical systems. Slow speed position measurement in applications such as motorized actuators has historically used resistive potentiometers. In high-speed applications such as servo motors, optical encoders have typically been used. Though potentiometers are inexpensive, they suffer from ...
