Monolithic Power Systems MP24894

Beschreibung

The MP24894 is a high-efficiency step-down controller. It is designed to operate in continuous current mode (CCM) 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-sense 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 case of output overload.

The MP24894 is available in TSOT6 package.
