Product Overview
The TC7660EOA is a charge pump DC-to-DC Voltage Converter for RS-232 negative power supply. The TC7660 device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5 to +10V input to a corresponding -1.5 to -10V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI). The on-board oscillator operates at a nominal frequency of 10kHz. Operation below 10kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground.
- 99.9% Efficient voltage conversion
- 98% Excellent power efficiency
- 80µA at 5VIN Low power supply
- Up to 3kV improved ESD protection
- No Dx 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.
