DESCRIPTION
Seriesof DC/DC converters delivers watts output power from wide input voltage range with efficiency. Output models meet variety system needs. units withstand transients milliseconds operate over full military temperature range -55°C +125°C. voltage (0.8 less) inhibit terminal (pin disables output. Leaving inhibit terminal unconnected connecting inhibit terminal open collector gate enables output. inhibit terminal open circuit voltage inhibit mode inhibit will source maximum "Inhibit Interface," Figure
CONVERTER DESIGN
converters incorporate flyback topology with typical constant switching frequency kHz. Isolation between input output circuits provided with transformer forward path temperature compensated optical link feedback control loop. feed-forward compensation design delivers audio rejection typical, with input ripple output ripple p-p. Output filter examples Figures provide suggested solutions systems where very output ripple required. Tightly coupled magnetics minimize cross regulation dual output models. Either output provide total available output power, providing opposite output carrying least total output power. converter's short circuit current protection restricts output current approximately 115% full load output current.
MIL-STD-461
Interpoint's FMGA-461 filter pass CE03 requirements MIL-STD-461C.
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.
