The TC7660COA is a charge pump voltage converter manufactured by Microchip Technology. This device is designed to convert a positive input voltage range of +1.5V to +10V into a corresponding negative output voltage range of -1.5V to -10V. It achieves highly efficient voltage conversion, with a typical efficiency of 99.9% and excellent power efficiency of 98%.
Key features include low power consumption, drawing only 80 µA typically at a 5V input. The TC7660COA requires only two external capacitors, simplifying circuit design and reducing component count and cost. It operates with a nominal internal oscillator frequency of 10 kHz, which can be adjusted for lower supply current applications by adding an external capacitor.
This voltage converter is available in 8-pin PDIP, SOIC, and CERDIP packages, suitable for various mounting requirements. It offers improved ESD protection up to 3 kV (HBM) and does not require an external diode for high-voltage operation. Applications include generating negative power supplies for RS-232 interfaces, creating ±5V supplies from a +5V source, and voltage multiplication.
The TC7660COA is a pin-compatible replacement for the industry-standard 7660 charge pump, offering enhanced performance and ease of use without the need for inductors, thus minimizing EMI.
