MP3366GC - White LED Driver

Download the MP3366GC datasheet PDF. This datasheet also covers the MP3366 variant, as both devices belong to the same white led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP3366 is a step-up converter with 6channel current sources designed to drive white LED arrays for backlighting in mid- to largesized LCD panels.

The MP3366 uses peak-current mode as its PWM control architecture.

The switching frequency can be programmed by a resistor.

Key Features

  • mixed digital PWM dimming and analog dimming with a 25% PWM duty cycle as a transfer point. The mix-dimming strategy helps to improve the dimming ratio. The MP3366 switches the PWM input signal from 100Hz to 20kHz to 23.5kHz to 29.5kHz automatically to eliminate audible noise. Full protection features include recoverable over-current protection (OCP), over-voltage protection (OVP), over-temperature protection (OTP), and short and open protection of any string on the LED. The MP3366 is available.

MP3366 Max 45mA/String, 6-String, Step-Up, White LED Driver with Combined Analog and PWM Dimming DESCRIPTION The MP3366 is a step-up converter with 6channel current sources designed to drive white LED arrays for backlighting in mid- to largesized LCD panels. The MP3366 uses peak-current mode as its PWM control architecture. The switching frequency can be programmed by a resistor. The MP3366 generates an output voltage up to 45V from a 3V-to-25V input supply. The MP3366 regulates the current in each LED string independently to the value set by an external current-setting resistor. The MP3366 applies six internal current sources in each LED string terminal to achieve a current balance with 1.5% current regulation accuracy between strings.
