MP3387L - White LED Driver

Monolithic Power Systems

Datasheet Details

The MP3387L 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 MP3387L uses peak-current mode as its PWM control architecture.

The Future of Analog IC Technology MP3387L Step-up, 6 strings, Max.

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, MP3387L automatically transfers the PWM input signal 100Hz to 20kHz frequency to 24kHz to 27.5kHz to eliminate the audible noise. MP3387L has rich protection modes to guarantee safety operation. The protection modes include recoverable OCP (over-current protection), OVP (over-voltage protection), OTP.
