AVAILABLE TC7660H HIGH FREQUENCY 7660 DC-TO-DC VOLTAGE CONVERTER
FEATURES GENERAL DESCRIPTION в–  The TC7660H is a pin-compatible, high frequency upgrade to the Industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +10V input to a
corresponding – 1.5V to – 10V output using only two lowcost capacitors, eliminating inductors and their associated
cost, size and EMI.
The TC7660H operates at a frequency of 120kHz
(versus 10kHz for the TC7660), allowing the use of 1.0ВµF
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. в–
