The TC7660COA is a charge pump voltage converter designed by Telcom Semiconductor. It is a pin-compatible replacement for the industry-standard 7660, converting input voltages from +1.5V to +10V to corresponding negative outputs.
Key features include a wide input voltage range of +1.5V to +10V, efficient voltage conversion up to 99.9% typical, and excellent power efficiency of 98% typical. It consumes low power, drawing only 80 µA typical at 5V input. The device requires only two external capacitors, simplifying design and reducing cost and EMI.
Applications for the TC7660COA include generating negative power supplies for RS-232 interfaces, creating ±5V supplies from a +5V source, and voltage multiplication. It is available in 8-pin SOIC, PDIP, and CERDIP packages, suitable for various mounting requirements.
The on-board oscillator operates at a nominal frequency of 10 kHz, but can be adjusted for lower supply current by adding an external capacitor. The device also features improved ESD protection (3 kV HBM).
The input voltage range is 1.5V to 10V.
Typical voltage conversion efficiency is 99.9% and power efficiency is 98%.
The typical quiescent current is 80µA at 5V input.
The nominal operating frequency is 10kHz.
The TC7660COA is available in 8-pin SOIC, 8-pin PDIP, and 8-pin CERDIP packages.
Multiple ranges are available: 0°C to +70°C (C suffix), -25°C to +85°C (I suffix), -40°C to +85°C (E suffix), and -55°C to +125°C (M suffix).
The device provides 3kV HBM ESD protection.
