MP24892 Datasheet Step Down White LED Driver

Manufacturer: Monolithic Power Systems

General Description

The MP24892 is a high-efficiency step-down converter that functions in continuous current mode to drive high-brightness LED.

It can take a wide input voltage range of 6V–45V.

The MP24892 employs a hysteretic control architecture to regulate a high-accuracy LED current, which is measured through an external high-side current-sensing resistor.
