DESCRIPTION
Seriesof DC/DC converters delivers watts output power labor saving surface mount package. wide input voltage range accepts varying voltages military, aerospace, space applications. Single output converters feature outputs volts while dual output models feature outputs ±12, volts. Transient protection volts milliseconds exceeds requirements MIL-STD-704A volt single dual models. volt single dual converters will withstand transients volts milliseconds.
PROTECTION Undervoltage lockout prevents Series converters from operating below approximately input voltage keep system current levels smooth, especially during initialization re-start operations. models include soft-start function prevent large current draw minimize overshoot. Series converters also provide short circuit protection limiting current approximately 125% full load.
MIL-STD-461
Interpoint's FMGA-461 filter pass CE03 requirements MIL-STD-461C.
CONVERTER DESIGN
Series DC/DC converters incorporate continuous flyback topology with constant switching frequency approximately kHz. Output voltage regulation accomplished primary side using current-mode pulse width modulation (PWM). Regulation affected output load; refer specifications tables more information. dual output models, total load output providing other output carries minimum total load. dual models used double output voltage connecting load between positive negative outputs, leaving common unconnected. example MGH2805D volt dual output) used output.
SURFACE MOUNT PACKAGE
DC/DC converters surface mounted with pick-andplace equipment manually. recommended that case attached with flexible epoxy adhesive silicone which thermally conductive watt /meter/°K). Internal components soldered with SN96 (melting temperature 221°C) prevent damage during reflow. Maximum reflow temperature surface mounting converter 220°C maximum seconds. SN60, recommended types solder. Hand soldering should exceed 300°C seconds pin. hermetically sealed metal cases available different lead configurations. Section case
INHIBIT FUNCTION
When open collector logic applied inhibit terminal, converter shuts down lowers output voltage near zero input current Leaving terminal open applying open collector logic high will enable converter.
