DESCRIPTION

The SP6832 device is a CMOS Charge Pump Voltage Inverter that can be implemented in designs requiring a negative voltage from a positive source as low as 1.15V. The SP6832 device is ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 700mA at a 5V supply. The SP6832 can output 25mA with a voltage drop of 500mV. These devices combine a low quiescent current with high efficiency of 85-90 over most of its load range. Applications include cell phones, PDAs, medical instruments and other portable equipment. The SP6832 is available in a space-saving 5-pin SOT23 Package.
