PD-94541E AHF SERIES 28V Input, Single/Dual Output HYBRID-HIGH RELIABILITY DC-DC CONVERTER AHF Description The AHF Series of DC-DC converters feature single or dual outputs over the full military temperature range. No derating in output power is required, making them suitable for use in rugged military applications. The low profile, small outline package is ideally suited to the tight board space requirements of many industrial and aerospace applications. Designed for nominal 28Vdc inputs, this family of converters will meet the requirements of MIL-STD-704D. The basic circuit utilizes a pulse width modulated, feed-forward topology at a nominal switching frequency of 550KHz. Input to output isolation is achieved through the use of transformers in the forward and feedback circuits. The proprietary magnetic feedback circuit provides for an extremely wide bandwidth control loop with a high phase margin. The closed loop frequency response of this converter family extends to approximately 50kHz, resulting in superior line and load transient characteristics. This feedback method is also inherently temperature and radiation insensitive. This gives the AHF Series an important advantage over converters that incorporate opto-couplers in their design. Features 16V to 40VDC Input Range (28VDC Nominal) Single and Dual Outputs 12W Output Power 22.8W/in3 Power Density Low Input / Output Noise (50mA / 60mVP-P max. respectively) Indefinite Short Circuit and Overload Protection Wideband Control Loop for Superior Transient Characteristics No derating for -55C to +125C Operation Constant Switching Frequency (550kHz Nominal) Standard Microcircuit Drawings Available Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA qualified process. For available screening options, refer to device screening table in the data sheet. Variations are electrical, mechanical and screening can be accommodated. Extensive computer simulation using complex modeling enables rapid design modification to be provided.

It is recommended that the Enable Pin be driven by an open collector device capable of sinking at least 400A of current. The open circuit voltage of the Enable Input is 151.0VDC. If the Inhibit function is not used, this Input can be left unconnected because it is internally pulled-up. Hence if TAMBIENT = +25C, the DC-DC converter case temperature will be approximately 100C if no heat sink or air flow is provided. To calculate the heat sink area required to maintain a specific case temperature rise, the above equation may be manipulated as follows: Thermal Management Assuming that there is no forced air flow, the package temperature rise above ambient (T) may be calculated using the following expression: As an example, if a maximum case temperature rise of 50C above ambient is desired, then the required effective heat sink area is: where A = Effective surface area in square inches (including heat sink if used), P = Power dissipation in watts. The total surface area of the AHF package is 4.9 square inches. If a worst case full load efficiency of 78% is assumed, then the case temperature rise can be calculated as follows: 16 2017-05-08 AHF SERIES (28V Input, Single/Dual Output) Block Diagrams Single Output EMI Filter 8 +Input Under-Voltage Detector Primary Housekeeping Supply 1 4 +Vout 3 Output Return 2 +Vout Enable Input 6 Drive Case Pulse Width FB Modulator CS Error Amp & Ref Input Return 7 Dual Output EMI Filter 8 +Input Under-Voltage Detector 1 Primary Housekeeping Supply 3 Output Return 4 -Vout Enable Input 6 Case Drive Pulse Width FB Modulator CS Error Amp & Ref Input Return 7 17 2017-05-08 AHF SERIES (28V Input, Single/Dual Output) Mechanical Outlines Non-Flanged 0.205 (5.21) 0.030 dia., 8 pins (0.760) 8 1 0.905 (22.99) 2 7 0.505 (12.83) 1.105 (28.07) 3 1.450 (36.83) 4 6 0.705 (17.91) 5 0.800 (20.32) 0.090 R Typ (2.290) 1.120 (28.45) 0.260 (6.600) 0.330 (8.380) MAX The Tolerance for X.XXX = 0.005" Flanged The Tolerance for X.XXX = 0.005" Pin Designation Tables Dual Output Single Output Standard Microcircuit Drawing Equivalence Table Standard Microcircuit Vendor Cage IR Hirel Standard Pin # Designation Pin # Designation Drawing Number Code Part Number 1 2 3 4 5 6 7 8 Enable Input NC Output Return +Output NC Case Ground Input Return +Input 1 Enable Input +Output Output Return -Output NC Case Ground Input Return +Input 5962-91600 52467 AHF2805S 5962-94568 52467 AHF2812S 5962-94563 52467 AHF2815S 5962-05205 52467 AHF2805D 5962-92111 52467 AHF2812D 5962-92351 52467 AHF2815D 18 2 3 4 5 6 7 8 2017-05-08 AHF SERIES (28V Input, Single/Dual Output) Device Screening Requirement MIL-STD-883 Method Temperature Range -- No Suffix ES HB CH -20C to +85C -55C to +125C -55C to +125C -55C to +125C Element Evaluation MIL-PRF-38534 N/A N/A N/A Class H Non-Destructive Bond Pull 2023 N/A N/A N/A N/A Internal Visual 2017 Yes Yes Yes Temperature Cycle 1010 N/A Cond B Cond C Cond C Constant Acceleration 2001, Y1 Axis N/A 500 Gs 3000 Gs 3000 Gs PIND 2020 N/A N/A N/A N/A Burn-In 1015 N/A Final Electrical (Group A) MIL-PRF-38534 & Specification 25C 25C -55C, +25C, +125C -55C, +25C, +125C PDA MIL-PRF-38534 N/A N/A N/A 10% Seal, Fine and Gross 1014 Cond A Cond A, C Cond A, C Cond A, C Radiographic 2012 N/A N/A N/A N/A 2009 Yes Yes Yes External Visual 48 hrs @ hi temp 160hrs @ 125C 160 hrs @ 125C Notes: Best commercial practice.
