The PTH12000 series of non-isolated power modules are small in size and high on performance. Using double-sided surface 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 important
design constraints.
The series operates from an input voltage of 12 V to provide step-down power
conversion to a wide range of output voltages. 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 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 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 throughhole and surface mount configurations.
