converter. It converts a +1.5V to +10V input to a corre-
sponding -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 fre-
quency of 10 kHz. Operation below 10 kHz (for lower
supply current applications) is possible by connecting
an external capacitor from OSC to ground.
The TC7660 is available in 8-Pin PDIP, 8-Pin Small
Outline (SOIC) and 8-Pin CERDIP packages in
commercial and extended temperature ranges.
