PTH12000

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 PTH12000 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 PTH12000 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.
