The TCM680EOA from Microchip Technology is a dual charge pump voltage converter designed to produce both positive and negative output voltages from a single input supply. It accepts an input voltage range of +2.0V to +5.5V and can generate outputs such as ±10V from a +5V logic supply or ±6V from a +3V lithium cell. This device features high efficiency, with typical power conversion efficiency at 85% and voltage conversion efficiency at 99%.
Requiring only four external capacitors, the TCM680EOA is clocked by an on-board 8 kHz oscillator. It offers low output source impedances, typically 140 Ω, and can provide maximum output currents of 10 mA for each output. The device is housed in an 8-pin SOIC package, making it suitable for applications where space is a consideration.
Common applications for the TCM680EOA include handheld instruments, portable cellular phones, LCD display bias generators, panel meters, and operational amplifier power supplies. Its ability to derive both positive and negative power supplies from a single input voltage makes it a versatile solution for various electronic designs.
