Screening: HSH Standard or HSH ES DESCRIPTION With a miniature footprint of just 0.8 square inches, the HSH SeriesTM of DC/DC converters delivers 1.5 watts of output power while saving significant board real estate. The wide input voltage range of 6 to 20 VDC accepts the varying voltages of military, industrial, or battery 15V bus power and tightly regulates output voltages to protect downstream components. Transient protection of 40 volts for up to 120 milliseconds. INHIBIT FUNCTION When an open collector TTL logic low is applied to the inhibit terminal, pin 7, the converter shuts down and lowers the output voltage to near zero and input current to as low 5 mA. Leaving the terminal open or applying an open collector TTL logic high will enable the converter. MIL-STD-461 Use Interpoint's FMSA-461 EMI filter to pass the CE03 requirements of MIL-STD-461C. CONVERTER DESIGN HSH Series DC/DC converters incorporate a flyback topology with a variable frequency, nominally 370 kHz. Output voltage is magnetically fed back to the input side of the PWM to regulate output voltage. Up to 80% of the load may be on one output providing that the other output carries a minimum of 20% of the total load. This dual model can be used as a single output voltage by connecting the load between positive and negative outputs, leaving the common unconnected resulting in double the output voltage. (ex: HSH1205D can be used as a 10 VDC output.) CONVENIENT PACKAGING The HSH Series converters are packaged in hermetically sealed metal cases which provide EMI/RFI shielding and protection from the environment.
