Ordering Information  
Pin-Out Information  
PT 6441r = 3.3 Volts  
PT 6442r = 2.5 Volts  
PT 6443r = 2.0 Volts  
PT 6444r = 1.8 Volts  
PT 6445r = 1.5 Volts

PT 6447r = 1.0 Volts  
The PT6440 Excalibur™ power modules  
are a series of high performance Integrated  
Switching Regulators (ISRs), housed in a  
thermally efficient solderable copper case.  
These modules operate from input voltages  
as low as 3.1V to produce a high-output low-  
voltage power source; ideal for powering the  
industry’s latest DSP and microprocessors.  
The series includes standard output bus  
voltages as low as 1.0VDC.  
The innovative copper case construction  
provides superior thermal performance in a  
small footprint. Both through-hole and  
surface mount pin configurations are avail-  
able. The PT6440 series operating features  
include external output voltage adjustment,  
an On/Off inhibit, and short-circuit protection.  
A 100µF input, and 330µF output capacitor  
are required for proper operation.
