DESCRIPTION

The MGA Series™ of DC/DC converters delivers 5 watts of output power from a wide input voltage range of 16 to 40 VDC with up to 74% efficiency. Output models of 5, 12, 15, ±5, ±12 and ±15 VDC meet a variety of system needs. All units withstand transients of up to 50 V for up to 50 milliseconds and operate over the full military temperature range of -55°C to +125°C. C ONVERTER D ESIGN The MGA converters incorporate flyback topology with a typical constant switching frequency of 500 kHz. Isolation between input and output circuits is provided with a transformer in the forward path and a temperature compensated optical link in the feedback control loop. The feed-forward compensation design delivers an audio rejection of 50 dB, typical, with input ripple as low as 50 mA p-p and output ripple as low as 100 mV p-p. Output filter examples in Figures 3 and 4 provide suggested solutions for systems where very low output ripple is required. Tightly coupled magnetics minimize cross regulation in the MGA dual output models. Either output can provide up to 80% of the total available output power, providing the opposite output is carrying at least 20% of the total output power. The converter’s short circuit current protection restricts the output current to approximately 115% of the full load output current. INHIBIT FUNCTION The MGA converter’s inhibit terminal disables internal switching, resulting in no output and very low quiescent input current. Applying a TTL low voltage (0.8 V or less) to the inhibit terminal (pin 1) disables the output. Leaving the inhibit terminal unconnected or connecting the inhibit terminal to an open collector gate enables the output. The inhibit terminal has an open circuit voltage of 9 to 11 V. In the inhibit mode the inhibit pin will source a maximum of 4 mA. See “Inhibit Interface,” Figure 2. MIL-STD-461 Use Interpoint’s FMGA-461 EMI filter to pass the CE03 require- ments of MIL-STD-461C. SURFACE M OUNT PACKAGE The MGA DC/DC converters can be surface mounted with pick-and- place equipment or manually. It is recommended that the case be attached with flexible epoxy adhesive or silicone which is thermally conductive (>1 watt /meter/°K). Internal components are soldered with SN96 (melting temperature 221°C) to prevent damage during reflow. Maximum reflow tempera- ture for surface mounting the MGA converter is 220°C for a maximum of 30 seconds. SN60, 62, or 63 are the recommended types of solder. Hand soldering should not exceed 300°C for 10 seconds per pin. The hermetically sealed metal cases are available in two different lead configurations. See Section B8, cases D1 and D2.
