TC962
General Description
The TC962 is an advanced version of the industry standard TC7662 high voltage DC-to-DC converter. Using improved design techniques and CMOS construction, the TC962 can source as much as 80mA versus the 7662’s 20mA capability. As an inverter, the TC962 can put out voltages as high as 18V and as low as 3V without the need for external diodes. The output impedance of the device is a low 28Ω (with the proper capacitors), voltage conversion efficiency is 99.9%, and power conversion efficiency is 97%. The low voltage terminal (pin 6) required in some TC7662 applications has been eliminated. Grounding this terminal will double the oscillator frequency from 12kHz to 24kHz.
