TC682EOA Description

Short technical summary and product information.

The TC682EOA from Microchip Technology is a versatile CMOS charge pump converter designed to generate a negative voltage from a single positive supply. It features a wide input voltage range of +2.4V to +5.5V and boasts high conversion efficiencies, with voltage conversion reaching 99.9% and power conversion at 92% typical.

 

This device requires only three external capacitors for full circuit implementation and operates with a low supply current of 185 μA. The TC682EOA provides an output current of up to 10 mA with a low output source impedance of typically 140 Ω. Its on-board oscillator operates at a typical frequency of 12 kHz.

 

The TC682EOA is housed in a space-saving 8-pin SOIC package, making it suitable for applications where board space is limited. It is designed for applications such as generating -10V from a +5V logic supply or -6V from a 3V lithium cell. Other applications include portable handheld instruments, cellular phones, LCD display bias generators, panel meters, and operational amplifier power supplies.

 

The operating temperature range for the TC682EOA is -40°C to +85°C, ensuring reliable performance in various environmental conditions. Its surface mount capability further enhances its ease of integration into electronic designs.
