3 AMP ADJUSTABLE

INTEGRATED SWITCHING REGULATOR

Revised 5/15/98

• Single-Device 5V to 3V Power

• 85% Efficiency

• Small SIP Footprint

• Adjustable Output Voltage

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

output 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.

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) operation. This high-

performance ISR allows easy integration

Please note that this product does not

include short circuit protection.
