MAX8848Z : 19-5233; Rev 0; 4/10 www.DataSheet4U.com TION KIT EVALUA BLE A IL A V A High-Performance Negative Charge Pump for 7 White LEDs in 3mm x 3mm Thin QFN General Description The MAX8848Y/MAX8848Z negative charge pumps drive up to 7 white LEDs with regulated constant current for display backlight applications. By utilizing an inverting charge pump and extremely low-dropout adaptive current regulators, these ICs achieve very high efficiency over the full 1-cell Li+ battery voltage range even with large LED forward voltage mismatch. The 1MHz fixedfrequency switching allows for tiny external components. The regulation scheme is optimized to ensure low EMI and low input ripple. The MAX8848Y/MAX8848.
