VOLTAGE (LV) 5 VOUT General Description
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). Applications 1 RS-232 Negative Power Supply
Simple Conversion of +5V to В±5V Supplies
Voltage Multiplication VOUT = В± n V+
Negative Supplies for Data Acquisition Systems
and Instrumentation 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 …
