TC7660 Charge Pump Voltage Converter

TC7660 Charge Pump DC-to-DC Voltage Converter

The TC7660 device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5V to +10V input to a corresponding -1.5V 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 10 kHz. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground.

Features of TC7660

  • Wide Input Voltage Range : +1.5V to +10V
  • Efficient Voltage Conversion (99.9%, typ)
  • Excellent Power Efficiency (98%, typ)
  • Low Power Consumption : 80 µA (typ) @ VIN = 5V
  • Low Cost and Easy to Use Only Two External Capacitors Required
  • Available in 8-Pin Small Outline (SOIC), 8-Pin PDIP and 8-Pin CERDIP Packages
  • Improved ESD Protection (3 kV HBM)
  • No External Diode Required for High-Voltage Operation

Applications of TC7660

  • RS - 232 Negative Power Supply
  • Simple Conversion of +5V to ±5V Supplies
  • Voltage Multiplication VOUT = ± n V+
  • Negative Supplies for Data Acquisition Systems and Instrumentation
