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:

1. Minimal required external components

2. Push pull topology

3. High precision reference and frequency control

4. External programmability of the key parameters

5. Flexible Dimming mode Control:

(1) Selective dimming polarity
(2) Analog, internal burst and external burst (LPWM) dimming control
(3) 0-2V DC voltage or external PWM direct dimming control without external circuits
(4) Dimming range programmable (100%~0%)

6. Comprehensive protection coverage:
(1) Output over voltage protection (OVP)
(2) Output over current protection (OCP)
(3) Open lamp protection and short lamp protection
(4) Arcing protection

7. Available in SOP16 package, RoHS compliant
