describe
The CMOS charge pump voltage inverter of the SP6828/6829 devices can implement designs that require a negative +3 V battery supply. The SP6828/6829 devices are ideal for battery-powered and board-level voltage conversion applications with a typical operating current of the SP6829 SP6828 and 40mA to 20mA. Both devices can output a 500mV drop of 25mA. These devices combine low quiescent current, which is ideal for high efficiency (>95%), over their load current range for most designs using +3.3 V or 3.6 V Li-Ion batteries. Applications include cell phones, PDAs, medical instruments and other portable devices. The SP6828/6829 devices are available in the space saving 5-pin SOT23 package.
