GENERAL DESCRIPTION
The TC7660H is a pin-compatible, high frequency up-
grade to the Industry standard TC7660 charge pump volt-
age 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 EMI.
The TC7660H operates at a frequency of 120kHz (ver-
sus 10kHz for the TC7660), allowing the use of 1.0
μ
F
external capacitors. Oscillator frequency can be reduced
(for lower supply current applications) by connecting an
external capacitor from OSC to ground.
The TC7660H is available in 8-pin DIP and small outline
(SOIC) packages in commercial and extended temperature
ranges.
