2 DESCRIPTION of HSA28 Series high reliability best DC DC Converter

The operating principle is that the sampling signal of output voltage, coupled by the opto-coupler, works together with the sampling signal of input loop current to regulate the pulse width of the controller. The double close loop control can create constant voltage output and short circuit protection.

Thick film hybrid techniques provide the HSA28 Series of converters with reliability levels and optimum miniaturization. The design and manufacturing process of HSA28 Series of converters are in compliance with General Standards of Hybrid Integrated Circuits and detailed standards of manufacturing. Connected to a HFD-CE03 filter, the HSA28 Series of converters can achieve better electromagnetic compatibility (EMC) performance.
