Description

The PTH12000WAH is a 1-output 33W through hole-mount non-isolated Adjust Module using double-sided surface mount construction and synchronous rectification technology, these regulators deliver up to 6A 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 important design constraints. The series operates from an input voltage of 12V to provide step-down power conversion to a wide range of output voltages. W-suffix devices are adjustable from 1.2 to 5.5V and L-suffix devices are adjustable from 0.8 to 1.8V. The output 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 pre-bias. A non-latching over-current trip provides protection against load faults.
