MPQ3387L White LED Driver

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. The switching frequency can be programmed by a resistor. It gener.

MPQ3387L 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
