The TCM680EOA is a dual charge pump voltage converter manufactured by Microchip Technology Inc. This device is designed to produce output voltages of +2VIN and -2VIN from a single input voltage ranging from +2.0V to +5.5V. Common applications include generating ±10V from a +5V logic supply or ±6V from a +3V lithium battery.
The TCM680EOA features high efficiency, with typical power conversion efficiency at 85% and voltage conversion efficiency at 99%. It requires only four external capacitors and is clocked by an onboard 8 kHz oscillator. The device offers low output source impedances, typically 140 Ω, providing maximum output currents of 10 mA for each output.
Packaged in an 8-pin SOIC, the TCM680EOA is suitable for various applications requiring both positive and negative power supplies derived from a single input voltage. These applications include handheld instruments, portable cellular phones, LCD display bias generators, panel meters, and operational amplifier power supplies.
Key electrical characteristics include an input voltage range of 2.0V to 5.5V and the ability to generate ±10V from a +5V supply. The operating temperature range is -40°C to +85°C, and it has an absolute maximum input voltage of +5.8V and absolute maximum output voltages of +11.6V and -11.6V.
The input voltage range is 2.0V to 5.5V.
With a 5V input, it produces ±10V outputs; with a 3V input, it produces ±6V outputs.
Each output can deliver up to 10 mA.
The operating temperature range is -40°C to +85°C.
The TCM680EOA is available in an 8-pin SOIC surface-mount package.
The typical power conversion efficiency is 85%.
The on-board oscillator frequency is 8 kHz.
