The TC7662BCPA is a charge-pump DC-to-DC Voltage Converter converts a 1.5 to 15V input to a corresponding -1.5 to -15V output using only two capacitors, eliminating inductors and their associated size and EMI. It is a pin-compatible upgrade to the Industry standard TC7660 charge-pump voltage converter. 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 is also possible by connecting an external capacitor from OSC to ground.
Boost pin for higher switching frequency
Easy to use - Requires only 2 external non-critical passive components
96% High power efficiency
Improved direct replacement for industry standard ICL7660 and other second source devices
