2 DESCRIPTION of HFL28 Series High Reliability DC/DC Converters The HFL28 Series of DC/DC converters offer up to 65 watts of output power with high reliability.

The converters are packaged in hermetically sealed metal cases, making them ideal for use in aviation, aerospace and other high reliability applications.

The HFL28 series of converters use a pulse width modulated and single ended forward 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 input loop current to regulate the pulse width of the controller.

The magnetic feedback technology can avoid magnetic saturation and improve products reliability effectively.
