DESCRIPTION

With a miniature footprint of just 0.8 square inches, the HSH Series™ 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, indus- trial, or battery 15V bus power and tightly regulates output voltages to protect downstream components. Transient protection of 40 volts for up to 120 milliseconds. CONVERTER DESIGN HSH Series DC/DC converters incorporate a flyback topology with a variable frequency, nominally 370 kHz. Output voltage is magneti- cally fed back to the input side of the PWM to regulate output volt- age. 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 uncon- nected resulting in double the output voltage. (ex: HSH1205D can be used as a 10 VDC output.) INHIBIT FUNCTION When an open collector TTL logic low is applied to the inhibit termi- nal, 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. CONVENIENT PACKAGING The HSH Series converters are packaged in hermetically sealed metal cases which provide EMI/RFI shielding and protection from the environment. Weight: 12 grams max.
