(19,05 mm x 12,7 mm)  
On/Off Inhibit  
Description  
Pin Configuration  
put voltage is set within the adjustment  
range using a single external resistor.  
Operating features include an on/off  
inhibit, output voltage adjust (trim), and  
the ability to start up into an existing  
output voltage or prebias. A non-latching  
over-current trip provides protection  
against load faults.  
Target applications include telecom,  
industrial, and general purpose circuits,  
including low-power dual-voltage systems  
that use a DSP, microprocessor, or ASIC.  
Package options include both through-  
hole and surface mount configurations.  
The PTH12000 series of non-isolated  
power modules are small in size and high  
on performance. Using double-sided sur-  
face mount construction and synchronous  
rectification technology, these regulators  
deliver up to 6 A of output current while  
occupying a PCB area of about half the  
size of a standard postage stamp. They  
are an ideal choice for applications where  
space, performance and cost are impor-  
tant design constraints.

The series operates from an input volt-  
age of 12 V to provide step-down power  
conversion to a wide range of output volt-  
ages. W-suffix devices are adjustable from  
1.2 V to 5.5 V, and L-suffix devices are  
adjustable from 0.8 V to 1.8 V. The out-
