HIGH CURRENT CHARGE PUMP DC-TO-DC CONVERTER  
FEATURES  
GENERAL DESCRIPTION  
■ Pin Compatible With TC7662/ICL7662/SI7661  
■ High Output Current ....................................... 80mA  
■ No External Diodes Required  
■ Wide Operating Range ............................. 3V to 18V  
■ Low Output Impedance ............................. 28Ω Typ.  
■ No Low Voltage Terminal Required  
■ Application Zener On Chip  
The TC962 is an advanced version of the industry-  
standard 7662 high-voltage DC-to-DC converter. Using  
improved design techniques and CMOS construction, the  
TC962 can source as much as 8mA 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 7662  
applications has been eliminated. Grounding this terminal  
will double the oscillator frequency from 12kHz 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  
(such as paralleling), driving this pin directly will cause the  
internal oscillator to sync to the external clock.
