Description
General part information
TC7662B Series
The TC7662B is a pin-compatible upgrade to the Industry standard TC7660 charge pump voltage converter. It converts a +1.5V to +15V input to a corresponding – 1.5 to – 15V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10kHz. Frequency is increased to 35kHz when pin 1 is connected to V + , allowing the use of smaller external capacitors. Operation below 10kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground (with pin 1 open). The TC7662B is available in both 8-pin DIP and 8-pin small outline (SO) packages in commercial and extended temperature ranges.
