DESCRIPTION The MP24892 is a high-efficiency step-down converter that functions in continuous current mode to drive high-brightness LED. It can take a wide input voltage range of 6V–45V. The MP24892 employs a hysteretic control architecture to regulate a high-accuracy LED current, which is measured through an external high-side current-sensing resistor. Moreover, this control scheme provides optimal circuit stabilization and a very quick response time without loop compensation. Its low 202mV average feedback voltage reduces power loss and improves the converter efficiency. The MP24892 implements PWM and analog dimming together through the DIM pin. The MP24892 includes thermal overload protection that prevents damage in the event of an output overload.
