A series of high performance CCFL backlight controller

Following the successful launch of a series of Green model AC-DC PWM IC power control, angbao electronic has also launched a series of CCFL Controller IC, which can be widely used in LCD-Monitor, LCD-TV, Notebook and industrial equipment, automotive and handheld equipment in liquid crystal display.

At present, bright electronics launched CCFL Controller IC products include: OB3316/OB3316N, OB3318/OB3318N, OB3328/OB3328N, OB3329/OB3329N, the whole series of chips are used DIP-16, SOP-16, TSSOP-16 three package.

Compared with the CCFL Controller IC the other general, series chip angbao have their distinct characteristics: reference voltage and frequency control of the entire series chip with high precision, support system wide voltage input, system parameter setting can be flexible to meet the different requirements of customers design system. At the same time chipset also provides various forms of failure and safety protection. Chip peripheral circuit design is very simple, can greatly reduce the cost of the system, the user is very attractive.

OB3328/OB3328N, OB3329/OB3329N for the full bridge architecture of the high system efficiency of the inverter backlight power system. OB3318/OB3318N is suitable for the inverter backlight power system - bridge structure, OB3316/OB3316N is suitable for the inverter backlight power system, the push-pull structure in OB3329/OB3329N system also has high and low voltage compensation function.

In the dimming control, angbao CCFL Controller IC series chip can provide flexible dimming mode, including internal simulation, Burst and external LPWM dimming control, direct dimming control 0-3V DC voltage (no external circuit), Burst internal and external combination of analog dimming control, for the customer to choose according to need. Among them, OB3316, OB3318, OB3328, OB3329 application Yu Zheng dimming mode, OB3316N, OB3318N, OB3328N and OB3329N used in negative dimming mode, the need for different dimming mode users can meet the design requirements.

OB3329/OB3329N lighting frequency using automatic sweep mode, OB3316/OB3316N, OB3318/OB3318N, OB3328/OB3328N lighting frequency adjustable frequency mode. Bao Bao Electronics launched by the CCFL Controller IC series of products in full compliance with the Pb-free and ROHS of the green environmental requirements, and can be provided through the certification of Bao Bao electronic SGS report, with a high cost.
