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.

The MP2489 is a high efficiency step-down converter designed in continuous current mode for driving the high brightness Light Emitting Diodes (LED) from wide input voltage 6V60V. The MP2489 employs 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 optimized circuit stabilization and very quick response time without the loop compensation. Its low 202mV average feedback voltage reduces power loss and improves the converter efficiency. The MP2489 implements PWM and analog dimming together with DIM pin. The MP2489 includes thermal overload protection preventing damage in the event of an output overload. The MP2489 is available in small QFN6 (3x 3mm), TSOT23-5 and SOIC8E packages.
