Fairchild Semiconductor introduces the industry's most integrated CCFL backlight inverter drive ICs for LCD backlight systems
Article Type: New products From: Microelectronics International, Volume 25, Issue 2.
Fairchild Semiconductor has now produced an integrated CCFL backlight inverter drive ICs providing space and cost savings, superior system reliability and simplified design for N-N half-bridge, push-pull, and P-N full- bridge LCD backlight inverter designs. The FAN7316 and FAN7317, featuring a wide input voltage range, and built-in open lamp protection (OLP) and open lamp regulation (OLR*) circuit, eliminate up to 30 external components in four lamp circuit inverter designs compared to similar devices on the market. These highly integrated CCFL backlight inverter drive ICs also feature selectable dimming polarity and analogue and burst dimming functions, which simplify design and speed time-to-market.
Industry-leading benefits of the FAN7316 and FAN7317 include:
- •
Space and cost savings. Eliminating the need for external IC_VCC regulation circuitry and OLP and OLR* detection circuitry and P- MOSFET driving circuitry* with its wide input voltage range (FAN7316: 4.5-24V, FAN7317: 6- 25.5V) and built-in OLP and OLR* detection circuitry. This eliminates up to 30 external components.
- •
System reliability. Offering the industry's most comprehensive protection functions including built- in OLP circuit, OLR, short circuit protection, thermal shutdown, soft- start and arc protection.
- •
Design flexibility. Featuring a wide input voltage range, selectable dimming polarity, analog and burst dimming mode and PWM dimming by an external pulse signal, the FAN7316 and FAN7317 offer flexibility in designing N-N half- bridge, push-pull and P-N full- bridge LCD backlight inverters.
Fairchild offers a comprehensive CCFL backlight inverter portfolio including Buck-Royer, push-pull, half and full- bridge topologies complemented by Fairchild's single and dual MOSFETs.
The FAN7316 and FAN7317 are available in a 20 pin SOIC lead (Pb)- free package that meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C. Both utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb- free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
