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