OZ9998GN datasheet

Description

OZ9998A, OZ9998GN are high effi ciency, DC/DC controllers that drive up to eight (8) strings of LEDs connected in parallel confi guration, with multiple LEDs in each string connected in series. They provide eight (8) LED current sense inputs in an “OR” confi guration to improve backlight reliability. This allows the backlight to remain functioning in the event that any string (s) is damaged during normal  peration.

Features

• High power DC/DC boost converter controller
• Drives up to 8 strings in parallel
• Integrated LED current balance control circuit
• User-defi ned string selection
• External PWM dimming control
• Time-shift PWM phase dimming control for low audible noise
• Multi-chip parallel operation for more than 8 LED strings
• MOSFET over-current protection
• LED short circuit and open string protection

[…]

Applications:

• LCD Monitor
• LCD TV
