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 80 mA
versus the 7662’s 20 mA 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
28
Ω (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 12
kHz to 24 kHz. 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.
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 12
Ω 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 Section 3.0 “Applications
Information” Applications Information).
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.
