Microchip Technology, Inc. Voltage Regulators - DC DC Switching Regulators TC682EPA

The TC682EPA is a CMOS charge pump converter designed to provide an inverted output voltage that is double the input voltage from a single positive supply. It operates within a wide input voltage range of +2.4V to +5.5V and can generate negative output voltages of -6V or -10V, making it suitable for applications such as portable handheld instruments, cellular phones, and operational amplifier power supplies. The device features a high voltage conversion efficiency of up to 99.9% and a power conversion efficiency of 92%. It requires only three external capacitors for full circuit implementation and has a low supply current of 185 ¬µA. The TC682EPA is available in an 8-pin PDIP package and operates over a temperature range of -40¬8C to +85¬8C. Its low output source impedance allows for output currents up to 10 mA, making it a compact and efficient solution for generating negative voltages in various electronic applications.
