(Verified) High-power LED constant current driver based on MP24894

Overview

The chip itself supports up to 60V, but this design recommends an input voltage of 12V-24V

The output current can be set by the high-end sampling resistor. Please refer to the specification for details.

The chip supports PWM dimming, but the dimming pin is not lead out because I can’t use it.

Output load test, two 9V10W 5530 lamp beads are connected in parallel, the power supply is 24V1A, the voltage and current measured at the LED end are as follows, the efficiency is pretty good
