Description  
Pin Configuration  
put voltage of the PTH05030W can be  
set to any value over the range 0.8 V to  
3.6 V, using a single resistor.  
The PTH05030 is a series of high-  
current non-isolated power modules  
from Texas Instruments. This product is  
characterized by high efficiencies, and  
up to 30 A of output current, while oc-  
cupying a mere 1.64 in² of PCB area. In  
terms of cost, size, and performance, the  
series provides OEM’s with a flexible  
module that meets the requirements of  
the most complex and demanding mixed-  
signal applications. These include the  
most densly populated, multi-processor  
systems that incorporate high-speed  
DSP’s, microprocessors, and ASICs.  
The series uses double-sided surface  
mount construction and provides high-  
performance step-down power conversion  
from a 5-V input bus voltage. The out-

This series includes Auto-Track™.  
Auto-Track simplifies power-up and  
power-down supply voltage sequencing  
in a system by enabling modules to track  
each other, or any other external voltage.  
Each model also includes an on/off  
inhibit, output voltage adjust (trim), and  
margin up/down controls. An output  
voltage sense ensures tight load regulation,  
and an output over-current and thermal  
shutdown feature provide for protection  
against external load faults.
