A venture in retrotronics
The pt1-OKLT6W12-5V5max is a robust and stable power supply providing four outputs, adjustable from 0.59V to 5.5V, at a maximum of 6A in total. The board is built around a Murata OKL-T/6-W12 DC-DC switching (buck) converter, not requiring a heat sink.
The input voltage can be anywhere between 4.5V and 14V, supplied through the screw connector or the barrel jack connector.
The module features an on-board fuse, protecting the circuit against input polarity reversal. The power output is protected against short circuits and over temperature. The converter will automatically restore operation 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).
Other signals available are SEQUENCE/TRACKING, PGOOD and SENSE.
