Features

28V Input, Single Output The AMF28XXS series of DC-DC converter modules has been specifically designed for operation in moderate radiation environments supplementing the higher radiation performance available in the International Rectifier ART, ARH and G-Series converters. Environments presented to space vehicles operating in low earth orbits, launch boosters, orbiting space stations and similar applications requiring a low power, high performance converter with moderate radiation hardness performance will be optimally served by the AMF28XXS Series. The AMF28XXS has been designed for high density using chip and wire hybrid technology that complies with the class H requirements of MIL-PRF-38534. Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA qualified processes. For available screening options, refer to device screening table in the data sheet. Applicable generic lot qualification test data including r adiation performance can be made available on request. Consult IR San Jose for special requirements. AMF28XXS SERIES The physical configuration of the AMF28XXS series permits mounting directly to a heat dissipation surface without the necessity of signal leads penetrating the heat sink surface. This package configuration permits greater independence in mounting and more mechanical security than traditional packages. International Rectifier’s rugged ceramic seal pins are used exclusively in the package thereby assuring long term hermeticity. HYBRID - HIGH RELIABILITY RADIATION TOLERANT DC-DC CONVERTER PD-94689D

Application Information

Inhibit Function (Enable) EMI Filter Device Synchronization Notes to Specifications Connecting the enable input (Pin 1) to input common (Pin 7) will cause the converter to shut down. It is recommended that the enable pin be driven by an open collector device capable of sinking at least 400 µA of current. The open circuit voltage of the enable input is 10 +1.0 VDC. 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). Interenational Rectifier provides synchronization of multiple AMF type converters to match switching frequency of the converter to the frequency of the system clock, thus eliminating this type of noise. 1 Parameter guaranteed by line and load regulation tests. 2 Bandwidth guaranteed by design. Tested for 20Hz to 2.0MHz. 3 Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in exce ss of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuit ry, appearing as a short circuit during turn on. 4 Parameter shall be tested as part of design characterization and after design or process changes. Therefore this Parameters shall be guaranteed to the limit specified. 5 Load step transition time between 2.0 and 10 microseconds.

6 Recovery time is measured from the initiation of the transient to where V

OUT has returned to within ±1 % of V OUT at 50 percent load. 7 Input step transition time between 1.0 and 10 microseconds. Parameter guaranteed by design but not 100% tested. 8 Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal fro m the inhibit pin while power is applied to the input. +Output Output Return Pulse Width Modulator Primary Housekeeping Supply EMI Filter Under-Voltage Detector +Input Enable Sync Input Input Return Error Amp & Ref FB CS Drive Case
