Pin-Out Information

Description

Pin Function

The PT5500 Excalibur™ power modules

are a series of high-performance Integrated

Switching Regulators (ISRs). Rated 3A,

these modules operate from input voltages as

low as 3.1V to provide a local step-down

power source. They are an ideal compliment

to the industry’s latest high-performance DSPs

and microprocessors. The series includes

output voltage options as low as 1.0VDC.

The PT5500 series is packaged in a 5-pin

thermally efficient copper case. The case is

solderable, has a small footprint, and can

accommodate both through-hole and surface

mount pin configurations.
