Pin-Out Information  
Pin Function  
The PT5540 Excalibur™ power modules  
are a series of integrated switching regulators  
(ISRs) that provide a boost-voltage function.  
They are designed for use with +5V bus  
systems that require an additional higher  
voltage rail.

The modules are rated 12W and produce  
a fixed output voltage over the full industrial  
temperature range of -40°C to +85°C. The  
series includes the common output voltages,  
+12V and +15V. Applications include PCI  
cards, audio circuits, and battery operated  
instruments.  
The PT5540 series is packaged in a 3-pin  
thermally efficient copper case. The case is  
solderable, has a small footprint, and can  
accommodate both through-hole and surface  
mount pin configurations.

The PT5540 series is offered as a next  
generation replacement to the popular PT5040  
series. The PT5540 has a lower operating  
temperature range and improved start-up  
characteristics.
