Description
The A8530 high efficiency charge pump ICs offer a simple, low-cost white LED driver solution for driving four display backlight and two flash/torch/video mode white LEDs. Using a proprietary control scheme (1×, 1.5×, and 2×), the A8530 can deliver well-matched LED current while maintaining the highest efficiency and low EMI. The LED current is regulated over the entire range of Li+ battery voltage to provide uniform intensity.
LED brightness and on/off can be controlled for 4 display backlight LEDs and 2 flash/torch LEDs through 2 single-wire serial interface pins.Features and Benefits
▪ Proprietary adaptive control scheme (1×, 1.5×, 2×)
▪ 0.5% typical LED current matching
▪ 2 separate serial interfaces for dimming control
▪ Drives up to 6 white LEDs (4 display backlight, 2 flash/torch)
▪ 30 mA per LED channel for display backlight
▪ 100 mA per LED channel for flash/torch backlight
▪ 320 mA total output current capability
▪ Low EMI design and soft-start function
▪ Short circuit, overvoltage, thermal shutdown protection
▪ 0.75 mm very thin profile, 3 mm × 3 mm packageApplications include:
▪ White LED backlights for cellular phones, PDAs
▪ Digital cameras, camcorders
▪ Other portable device white LED backlighting
▪ 320 mA WLED flash/torch -
