OB3309 datasheet

Description :

OB3309 is a high integrated and high performance U-type Cold Cathode Fluorescent Lamp (CCFL) controller optimized for LCD monitor backlight application. Comprehensive protection functions are integrated, thus it provides a low-cost and high reliability LCD backlight solution with minimum system BOM count. OB3309 controls push pull topology and supports various dimming functions.


Features:

◆ Minimal required external components
◆ Push pull topology
◆ High precision reference and frequency control
◆ External programmability of the key parameters
◆ Flexible Dimming mode Control:
◇ Selective dimming polarity
◇ Analog, internal burst and external burst (LPWM) dimming control
◇ 0-2V DC voltage or external PWM direct dimming control without external circuits
◇ Dimming range programmable (100%~0%)
◆ Comprehensive protection coverage:
◇ Output over voltage protection (OVP)
◇ Output over current protection (OCP)
◇ Open lamp protection and short lamp protection
◇ Arcing protection
◆ Available in SOP16 package, RoHS compliant
