Product Description

The HHD*8 Series of DC/DC converters offer up to *0 watts of output power with high reliability. The HHD*8 series small size, light weight, and hermetically sealed metal packages make them ideal for use in aviation aerospace and other high reliability applications. 
The HHD*8 series of converters use forward pulse width modulated topology design. The operating principle is that the sampling signal of output voltage, coupled by the opto-coupler, works together with the sampling signal of loop current to regulate the pulse width of the controller. The double close loop control can create constant voltage output and short circuit protection. The magnetic feedback technology can effectively prevent the magnetic saturation of transformer and also products reliability can be improved. 
Thick film hybrid techniques provide the HHD*8 Series of converters with reliability levels and optimum miniaturization. The design and manufacturing process of HHD*8 Series of converters are in compliance with General Standards of Hybrid Integrated Circuits and detailed standards of manufacturing. Connected to a HFD-CE*3 filter, the HHD Series of converters can achieve better electromagnetic compatibility (EMC) performance.
