The PT6400 is a high performance
+5V to +3.3V, 3 Amp, 12-Pin SIP
(Single In-line Package) Integrated
Switching Regulator (ISR) designed
for stand alone (not parallelable) op-
eration. This high-performance ISR
allows easy integration of low-power
3.3V logic IC’s into existing 5V systems
without redesigning the central power
supply. Only two external capacitors are
required for proper operation. The out-
put voltage is easily adjustable with one
external resistor. The PT6406,7,8 can
be used to terminate high-speed data
buses such as Futurebus (+2.1V) or the
new GTL (+1.2V) logic buses.
Please note that this product does
not include short circuit protection.
