Screening: HSH Standard or HSH ES 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, 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. 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. 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. CONVENIENT PACKAGING The HSH Series converters are packaged in hermetically sealed metal cases which provide EMI/RFI shielding and protection from the environment. 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.) ® 1 DC/DC CONVERTERS HSH SERIES 1.5 WATT ABSOLUTE MAXIMUM RATINGS Input Voltage • 6 to 20 VDC Output Power • 1.5 W Lead Soldering Temperature (10 sec per lead) • 300°C Storage Temperature Range (Case) • –65°C to +150°C TYPICAL CHARACTERISTICS INHIBIT Inhibit – TTL Open Collector • Logic low (output disabled) • Referenced to input common • Logic high (output enabled) open collector RECOMMENDED OPERATING CONDITIONS Input Voltage Range • 6 to 20 VDC continuous, 600 mW max • 12 to 18 VDC continuous, 1.5 W max Case Operating Temperature (Tc) • +125°C to +150°C 1 watt • –55°C to +125°C 1.5 watt Output Voltage Temperature Coefficient • 100 ppm/°C typical Isolation • 100 megohm minimum at 500 V • Any pin to case except case pin Audio Rejection 40 dB, typical Conversion Frequency (kHz) • 90 min kHz, Vin=6V, ±Iout=60 mA, Tc=-55 to +125°C Inhibit Pin Voltage (unit enabled) • 7 to 8 V Electrical Characteristics:14 VDC Vin, ±100mA load, unless otherwise specified.
