The TC7660SVOA from Microchip Technology is a pin-compatible charge pump voltage converter designed to replace the industry-standard TC7660. It operates with an input voltage range of +1.5V to +12V and can generate corresponding negative output voltages from -1.5V to -12V. This device is highly efficient, offering up to 99.9% voltage conversion efficiency and 98% power efficiency, with a low quiescent current of 80 µA typical at 5V input.
Key features include an adjustable oscillator boost from 10 kHz to 45 kHz, enabling it to convert a +5V logic supply to a ±5V system. It requires only two external capacitors, simplifying circuit design and reducing component count. The TC7660SVOA is available in 8-pin SOIC and PDIP packages, making it suitable for various board space constraints. It also provides improved ESD protection up to 10 kV HBM and does not require an external diode for high-voltage operation.
Applications for the TC7660SVOA include generating negative power supplies for RS-232 interfaces, data acquisition systems, and instrumentation. Its ability to perform voltage multiplication (VOUT = ± n V+) and create negative supplies from positive inputs makes it a versatile component for power management in embedded systems.
The input voltage range for the TC7660SVOA is 1.5V to 12V.
The TC7660SVOA can produce output voltages where Vout = -Vin or Vout = 2Vin.
The typical active output current is 20 mA.
The typical quiescent current is 80 µA.
The operating temperature range is -40°C to +125°C.
The TC7660SVOA is available in SOIC and PDIP packages.
