CAT3626 - 6-Channel LED Driver

Description

The CAT3626 is a high efficiency 1x/1.5x fractional charge pump with programmable dimming current in six LED channels.

To ensure uniform brightness in LCD backlight applications, each LED channel delivers an accurate regulated current.

Features

  • Drives 6 LED channels Independent current on 3 pairs of LEDs I2C serial interface programming Adjustable current to 32mA in 0.5mA step Power efficiency up to 91% Fractional pump 1x/1.5x Low noise input ripple Fixed High Frequency Operation 1MHz “Zero” Current Shutdown Mode Soft start and current limiting Short circuit protection Thermal shutdown protection.
