Product Overview
The TC7660SEPA is a super charge-pump DC-to-DC Voltage Converter. It converts a 1.5 to 12V input to a corresponding -1.5 to -12V output using only two capacitors, eliminating inductors and its associated size and electromagnetic interference (EMI). Added features include an extended supply range to 12V and a frequency boost pin for higher operating frequency, allowing the use of smaller external capacitors. It is a pin-compatible replacement for the industry standard 7660 charge-pump voltage converter. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 45kHz when pin 1 is connected to V+. Operation below 10kHz is possible by connecting an external capacitor from OSC to ground.
- Easy to use - Only two external capacitors required
- No external diode required for high-voltage operation
- Converts 5V logic supply to ±5V system
- 99.9% Efficient voltage conversion
- 98% Excellent power efficiency
- 80µA at VIN = 5V Low power consumption
Applications
Power Management, Signal Processing, Industrial, Automation & Process Control
