Introduction

AI Translation

The TC7660S device is a pin-compatible replacement for the industry standard 7660 charge pump voltage converter. It converts a +1.5V to +12V input to a corresponding -1.5V to -12V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and electromagnetic interference (EMI). Added features include an extended supply range to 12V, and a frequency boost pin for higher operating frequency, allowing the use of smaller external capacitors. The on-board oscillator operates at a nominal frequency of 10 kHz. Frequency is increased to 45 kHz when pin 1 is connected to V+. Operation below 10 kHz (for lower supply current applications) is possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7660S is available in 8-Pin PDIP and 8-Pin Small Outline (SOIC) packages in commercial and extended temperature ranges.
