Introduction

AI Translation

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 low-cost 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 1.0μF 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. The TC7660H contains all the necessary circuitry to implement a voltage inverter, with the exception of two external capacitors, which may be inexpensive 1.0μF non-polarized capacitors. To improve low-voltage operation, the LV pin should be connected to GND. For supply voltages greater than 3.5V, the LV terminal must be left open to ensure latch-up proof operation and prevent device damage.
