MAX8647ETE+T

MAX8647ETE+T is an ultra-efficient charge pumps for six white/ 2 RGB LED with regulated constant current for display backlight and fun light applications. By utilizing an inverting charge pump and extremely low dropout adaptive current regulators, this IC achieves very high efficiency over the full 1-cell Li+ battery voltage range and even with large LED forward voltage mismatch. The 1MHz fixed-frequency switching allows for tiny external components. The regulation scheme is optimized to ensure low EMI and low input ripple. The MAX8647 include thermal shutdown, open and short-circuit protection. Suitable for white LED backlighting, single or dual display, wide-gamut RGB LED display backlighting, camera flash or RGB indicators, cellular phones and smartphones, PDAs, digital cameras, and camcorders applications.
