Features

28V Input, Dual Output The advanced feedback design provides fast loop response for superior line and load transient characteristics and offers greater reliability and radiation tolerance than devices incorporating optical feedback circuits. Three standard temperature grades are offered with screening options. Refer to Part Number section. They can be provided in a standard plug-in package for PC mounting or in a flanged package for more severe environments. Manufactured in a facility fully qualified to MIL-PRF- 38534, these converters are fabricated utilizing DLA and Land Maritime qualified processes. For available screening options, refer to device screening table in the data sheet. Variations in electrical, mechanical and screening can be accommodated. Extensive computer simulation using complex modeling enables rapid design modification to be provided. Contact IR San Jose with specific requirements. The ATR28XXD Series of DC-DC converters feature high power density and an extended temperature range for use in military and industrial applications. Designed to MIL-STD-704D input requirements, these devices have nominal 28VDC inputs with ±12V and ±15V dual outputs to satisfy a wide range of requirements. The circuit design incorporates a pulse width modulated single forward topology operating in the feed-forward mode at a nominal switching frequency of 550KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits. /G11016V to 40VDC Input Range (28VDC Nominal) /G110/G17712V and /G17715V Outputs Available /G110Indefinite Short Circuit and Overload Protection /G11035W/in Power Density /G11030W Output Power /G110Fast Loop Response for Superior Transient Characteristics /G110Operating Temperature Range from -55°C to +125°C /G110Popular Industry Standard Pin-Out /G110Resistance Seam Welded Case for Superior Long Term Hermeticity /G110Ceramic Feed-thru Pins /G110External Synchronization /G110High Efficiency /G110Shutdown from External Signal /G110Military Screening /G110 Standard Microcircuit Drawings Available PD-94550B

6 www.irf.com ATR28XXD Series Connecting the inhibit input (Pin 2) to input common (Pin 10) 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 400µA of current. The open circuit voltage of the inhibit input is 11.5 ±1.0VDC. Assuming that there is no forced air flow, the package temperature rise above ambient ( ∆T) may be calculated using the following expression: where A = the effective surface area in square inhes (in-cluding heat sink if used), P d = power dissipation in watts. The total surface area of the ATR standard package is 7.34 square inches. If a worse case full load efficiency of 78% is assumed, then the case temperature rise can be calculated as follows: Hence, if T AMBIENT = +25 °C, the DC/DC converter case temperature will be approximately 147 °C if no heat sink or air flow is provided.

Whenever multiple DC/DC converters are utilized in a single system, significant low frequency noise may be generated due to slight difference in the switching frequencies of the converters (beat frequency noise). Because of the low frequency nature of this noise (typically less than 10KHz), it is difficult to filter out and may interfere with proper operation of sensitive systems (communications, radar or telemetry). The International Rectifier ATR28XX converters provide a synchronizing input permitting synchronization of multiple converters to the frequency of the users system clock, thereby minimizing this type of noise.
