The PWS727 is a DC/DC converter that uses minimal PC board space and converts a single input into a 10 to 18VDC input with a bipolar voltage of the same value. The PWS728 converts three times the input value to a bipolar voltage of 4.7 to 6VDC. The converter is capable of delivering ±15mA (PWS727) ±12mA (PWS728) at rated voltage and up to ±30mA.
The PWS727 and PWS728 use a high frequency (800kHz nominal) surface mount oscillator, making it possible to minimize the size of the transformer.
The transformer is made up of a split bobbin isolation transformer using a ferrite core, which is encapsulated in a plastic package that allows for higher isolation voltage ratings. The design minimizes noise on the high-frequency radiated output by directly using a ground plane based on high-frequency components.
