General Description

The MPQ3387L is a step-up converter with 6channel current sources.

It is designed for driving the white LED arrays as backlighting of middle or large size LCD panel.

The MPQ3387L uses peak-current mode as its PWM control architecture.

Key Features

external digital PWM dimming and analog dimming, both of which sharing a single input with 25% PWM duty cycle as a transfer point. The mix-dimming strategy helps to improve the dimming ratio. Also, MPQ3387L automatically transfers the PWM input signal 100Hz to 20kHz frequency to 24kHz to 27.5kHz to eliminate the audible noise. MPQ3387L has rich protection modes to guarantee safety operation. The protection modes include recoverable OCP (over-current protection), OVP (over-voltage protection), OT.
