TC962CPA

The TC962CPA is an advanced version of the industry standard TC7662 high voltage charge-pump DC-to-DC Converter using improved design techniques and CMOS construction, the TC962 can source as much as 80mA versus the 7662 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 low 28W voltage conversion efficiency is 99.9% and power conversion efficiency is 97%. Grounding this terminal will double the oscillator frequency from 12 to 24kHz. This will allow the use of smaller capacitors for the same output current and ripple in most applications. Only two external capacitors are required for inverter applications. In the event an external clock is needed to drive the TC962, driving this pin directly will cause the internal oscillator to sync to the external clock.

• No external diodes required
• No low voltage terminal required
• OSC Frequency doubling pin for smaller output capacitors
