Hermetically sealed metal case HSDF28D15, HSDF28D15F 2 Scope of application of HSDF28D Series Transient Suppression DC/ DC Converters High-reliability electronic system for aviation and aerospace, etc 3 Descriptions of HSDF28D Series Transient Suppression DC/ DC Converters This series device is high reliable and is featured with surge protection (80v, 1s) for DC/DC converter.

Single ended flyback, pulse width modulated and transformer magnetic feedback topology design are used in this device.

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 loop control creates constant voltage output and short circuit protection.

Thick film hybrid techniques provide the HSDF28D Series of converters with high reliability and optimum miniaturization.

The design and manufacturing process of HSDF28D series converters are in compliance with MIL-PRF-38534 and detailed specifications
