Microchips TC7660SCPA are brilliant and efficient DC to DC converters. They boast an impressive 98% efficiency and a 99.9% voltage conversion. This DC convertor is rated to convert +1.5V to +12V into -1.5V and -12V output using only two capacitors. The TC7660SCPA also includes an on-board oscillator and operates at a base frequency of 10kHz. The oscillators frequency can increase to 45kHz when pin 1 is connected to V+. This device is in an 8-pin, PDIP package.
Features and benefits:
- On-board oscillator can boost from 10kHz, up to 45kHz (when pin 1 has V+.)
- Brilliant power efficiency of 98%
- Voltage conversion – 99.9%
- Industry standard 7660 charge pump converter
- Improved ESD protection – 10kV
- 8-pin, PDIP package
- Low power supply - 80μA @ 5VIN
- Converts +5V Logic Supply to ±5V System
- Conversions of +5V to ±5V
- Voltage multiplication
- RS-232 negative power supplies
- Negative supplies for data acquisition
