EV24894-J-00A

The EV24894-J-00A is an evaluation board for the MP24894GJ, a high-efficiency step-down controller. It is designed to function in continuous current mode to power LEDs of high-brightness with a wide input voltage range of 6V to 60V.

The MP24894 employs a hysteretic control architecture that accurately regulates LED current; with a feedback coming from an external high-side current-sensing resistor. This control scheme optimizes circuit stabilization and fast response time without loop compensation. Its low 200mV average feedback voltage reduces power loss and improves the converter’s efficiency.

The MP24894 implements PWM and analog dimming together through the EN/DIM pin.

The MP24894 includes thermal overload protection in the case of output overload.
