The pt1-OKIT3W32-4V5max is a robust and stable power supply providing four outputs, adjustable from 0.75V to 4.5V, at a maximum of 3A in total. The board is built around a Murata OKI-T/3-W32 DC-DC switching (buck) converter, not requiring a heat sink.
The input voltage can be anywhere between 9V and 32V, supplied through the screw connector or the barrel jack connector.
The module features an on-board fuse, protecting the circuit against sustained input reversal. The power output is protected against short circuits and over temperature. The converter will automatically restart as soon as the short circuit condition is removed.
Some translator logic has been added to the circuit to provide a (positive) logic ENABLE signal (e.g. 3.3/5V).
NOTE: the full output voltage range runs from about 0.75V to 4.5V; if you need a more limited range (to protect the hardware you will be connecting to this module), select one of the other (more restricted) ranges
NOTE: the module requires a different fuse depending on the input voltage (2A for ~12V input, 1A for ~24V input); make sure you select the right module for your application
NOTE: the module will only start when a high logic ENABLE signal is provided; if you need a module that is always on, select the type without the ENABLE signal logic
I've created this board as a low-voltage power supply for my LED applications (often based on the TI TLC5947 constant current LED driver), and to feed the filaments of the VFD display tubes I'm using in my projects.
