Product Overview
The TC7660SEOA is a super charge pump DC-to-DC Voltage Converter for RS-232 negative power supply. The TC7660S device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5 to +12V input to a corresponding -1.5 to -12V output using only two low-cost capacitors, eliminating inductors and their associated cost, 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. 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 (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground (with pin 1 open).
- Oscillator boost from 10 to 45kHz
- Converts +5V logic supply to ±5V system
- Efficient voltage conversion of 99.9%
- Excellent power efficiency of 98%
- Low power supply of 80µA at 5VIN
- Improved ESD protection-up to 10kV
- No external diode required for high voltage operation
Applications
Power Management, Test & Measurement, Sensing & Instrumentation
Warnings
ESD sensitive device, take proper precaution while handling the device. Market demand for this product has caused an extension in leadtimes. Delivery dates may fluctuate. Product exempt from discounts.
