Description  
Pin Configuration  
Pin Function  
Auto-Track simplifies the task of supply  
voltage sequencing in a power system by  
enabling modules to track each other, or  
any external voltage, during power up and  
power down.  
Other operating features include an  
on/off inhibit, output voltage adjust (trim),  
and margin up/down controls. To ensure  
tight load regulation, an output voltage  
sense is also provided. A non-latching  
over-current trip serves as load fault  
protection.  
The PTH05010 series of non-isolated  
power modules are small in size but big on  
performance and flexibility. Their high  
output current, compact footprint, and  
industry-leading features offers system  
designers a versatile module for powering  
complex multi-processor digital systems.  
The series employs double-sided surface  
mount construction and provides high-  
performance step-down power conversion  
for up to 15 A of output current from a  
5-V input bus voltage. The output volt-  
age of the PTH05010W can be set to any  
value over the range, 0.8 V to 3.6 V, using  
a single resistor.
