PT6400 Series

3 Amp 5V Input Adjustable

Integrated Switching Regulator

SLTS032A

(Revised 6/30/2000)

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.

•

Single-Device 5V to 3V Power

85% Efficiency

Small SIP Footprint

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

Please note that this product does

not include short circuit protection.
