MPQ2489 Datasheet Step Down White LED Driver

Manufacturer: Monolithic Power Systems

General Description

The MPQ2489 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 6V–55V.

The MPQ2489 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.
