Ordering Information

Pin Function

PT6472r = 2.5 Volts

PT6473r = 2.0 Volts

PT6474r = 1.8 Volts

PT6475r = 1.5 Volts

PT6476r = 1.2 Volts

PT6477r = 1.0 Volts

The PT6470 Excalibur™ series of integrated

switching regulators (ISRs) combines outstand-

ing power density with a comprehensive list of

features. They are an ideal choice for applications

where board space is a premium and performance

cannot be compromised. These modules provide a

full 14 A of output current, yet are housed in a

low-profile, 12-pin, package that is almost half

the size of the previous generation of products.

The integral copper case construction requires

no heatsink, and offers the advantages of solder-

ability and a small footprint (0.64 in² for suffix

‘N’). Both through-hole and surface mount pin

configurations are available.

The PT6470 series operates from a 3.3-V

input to provide a convenient point-of-load power

source for the industry’s latest high-performance

DSPs and microprocessors. The series includes

output voltage options as low as 1.0V DC.

Other features include external output voltage

adjustment, on/off inhibit, pre-bias startup, short

circuit protection, and an output remote sense.
