Features: PT6400 Series 3 Amp 5V Input Adjustable Integrated Switching Regulator SLTS032 A (Revised 6/30/2000) • Single-Devic e 5V to 3V Power • 85% Efficiency • Small SIP Footprint • Adjustable Out put Voltage The PT6400 is a high perfor mance +5V to +3.3V, 3 Amp, 12-Pin SIP ( Single In-line Package) Integrated Swit ching Regulator (ISR) designed for stan d alone (not parallelable) operation. T his high-performance ISR allows easy i ntegration of low-power 3.3V logic IC s into existing 5V systems without red esigning the central power supply. Only two external capacitors are required f or proper operation. The output voltage is easily adjustable with one external resistor. The PT6406,7,8 can be used t o 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.

Adjustable Output Voltage
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.
