DC -TO-DC CONVERTER
TC962
Pin 1, which is used as a test pin on the 7662, is a voltage
reference zener on the TC962. This zener (6.4V at 5 mA) has
a dynamic impedance of 12Ω and is intended for use where
the TC962 is supplying current to external regulator circuitry
and a reference is needed for the regulator circuit. (See
applications section.)
The TC962 is compatible with the LTC1044, SI7661,
and ICL7662. It should be used in designs that require
greater power and/or less input to output voltage drop. It
offers superior performance over the ICL7660S.

*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.
ELECTRICAL CHARACTERISTICS: V_DD = 15V, T_A = +25°C (See Test Circuit), unless otherwise indicated.
