MP24893

The MP24893 is a high efficiency step-down converter designed in continuous current mode for driving the high brightness LEDs from wide input voltage of 6V to 36V. The MP24893 employs hysteretic control architecture to regulate a highly accurate LED current, which is measured through an external high-side current-sense resistor. Moreover, this control scheme provides optimal circuit stabilization and a very quick response time without loop compensation. Its low 200mV average feedback voltage reduces power loss and improves the converter efficiency. The MP24893 implements PWM and analog dimming together through the DIM pin. The MP24893 includes under-voltage lockout, thermal overload protection to prevent damage in the event of an output overload. The MP24893 is available in TSOT23-5 and QFN6 packages.
