The TC7660EOA is a charge pump DC-to-DC voltage converter designed to convert an input voltage range of +1.5V to +10V into a corresponding negative output voltage of -1.5V to -10V. It operates with high efficiency, achieving typical voltage conversion efficiency of 99.9% and power efficiency of 98%. The device requires only two external capacitors for operation, simplifying the design and reducing costs by eliminating the need for inductors. This voltage regulator features a low power consumption of 80 µA at a 5V input and offers improved ESD protection rated at 3 kV HBM. The TC7660EOA is available in an 8-pin SOIC package suitable for commercial and extended temperature ranges. It is particularly useful in applications such as RS-232 negative power supplies, voltage multiplication, and negative supplies for data acquisition systems. The on-board oscillator operates at a nominal frequency of 10 kHz, with the option to lower the frequency for applications requiring reduced supply current.
