www.irf.com 5 amr28xxd series (28v input, dual output) block diagram application information inhibit function (enable) emi filter device synchronization an optional emi filter is available (afh461) that will reduce the input ripple current to levels below the limits imposed by mil-std-461 ce03. when multiple dc-dc converters are utilized in a single system, significant low frequency noise may be generated due to a small difference in the switching frequency of the converters (beat frequency noise). because of the low frequency nature of this noise (typically less than 10 khz), it is difficult to filter out and may interfere with proper operation of sensitive systems (communication, radar or telemetry). international rectifier provides synchronization of multiple amr type converters to match switching frequency of the converter to the frequency of the system clock, thus eliminating this type of noise. connecting the inhibit input to input common will cause the converter to shut down. it is recommended that the inhibit pin be driven by an open collector device capable of sinking at least 400 a of current. the open circuit voltage of the inhibit input is 10 1.0 v dc . 1. parameter guaranteed by line and load regulation tests. 2. up to 90 percent of full power is available from either output provided the total output does not exceed 30 watts. 3. bandwidth guaranteed by design, tested for 20 hz to 2 mhz. 4. load current split equally between +v out and ?v out . 5. 3 watt load on output under test. 3 watt to 27 watt load change on other output. 6. capacitive load may be any value from 0 to the maximum limit without compromising dc performance. a capacitive load in excess of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn-on. 7. parameter shall be tested as part of design characterization and after design or process changes, parameters shall be guaranteed to the limit specified in electrical specifications. 8. load step transition time between 2 and 10 microseconds. 9. recovery time is measured from initiation of the transient to where v out has returned to within 1% of vout at 50% load. 10. input step transient time between 2 and 10 microseconds. 11. turn-on dela y time measurement is for either a step application of power at the input or the removal of a g round si g nal from the inhibit p in while p ower is a pp lied to the in p ut. notes to specifications 8 7 +output output return pulse width modulator primary housekeeping supply emi filter under-voltage detector 1 3 10 2 +input enable sync input input return error amp & ref fb cs drive 6 -output 5 case
