DESCRIPTION The SP6830/6831 devices are CMOS Charge Pump Voltage Inverters that can be implemented into designs which require a negative voltage from a battery voltage source as low or a power supply rail voltage as high as +5.3V. The SP6830/6831 devices are ideal for both battery-powered and board level voltage conversion applications with a typical operating current of 70μA for the SP6830 and 200μA for the SP6831. These devices combine an ultra-low shutdown current of <1μA with high efficiency (>95% over most of its load-current range) which are ideal for designs using batteries such as cell phones, PDAs, medical instruments, and other portable equipment. The SP6830/6831 devices are available in a space-saving 6-pin SOT23-6 Package.


These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. +0.3V IOUT......................................................................50mA Storage to +150OC Lead Temperature (Soldering)..........................300OC Power Dissipation Per Package

Note 1: Minimum VIN required for VO = -VIN +0.2V. Note 2: During the shutdown mode, VIN is disconnected from VOUT. Note 3: Capacitors are approximately 20% of the output impedance where ESR =


VOUT x IOUT -VIN x (-VIN/RL) VOUT x IOUT VIN x IIN

PIN ASSIGNMENTS Pin 1-- VOUT Inverting charge pump output.

Pin 2 VIN Input to the positive power supply. Pin 3 C1- Negative terminal to the charge pump capacitor. Pin 4 GND Ground reference. Pin 5 SHDN Active LOW Shutdown input. Pin 6 C1+ Positive terminal to the charge pump capacitor.
