5、ON LEVEL C SHEET 2 DSCC FORM 2234 APR 97 1. SCOPE 1.1 Scope. This drawing documents five product assurance classes as defined in paragraph 1.2.3 and MIL-PRF-38534. A choice of case outlines and lead finishes which are available and are reflected in the Part or Identifying Number (PIN). When availabl
6、e, a choice of radiation hardness assurance levels are reflected in the PIN. 1.2 PIN. The PIN shall be as shown in the following example: 5962 - 92040 01 H X X Federal RHA Device Device Case Lead stock class designator type class outline finish designator (see 1.2.1) (see 1.2.2) designator (see 1.2.
7、4) (see 1.2.5) / (see 1.2.3) / Drawing number 1.2.1 Radiation hardness assurance (RHA) designator. RHA marked devices shall meet the MIL-PRF-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device. 1.2.2 Device type(s). The device typ
8、e(s) identify the circuit function as follows: Device type Generic number Circuit function 01 AHE2812D/CH DC/DC converter, 15 W, 12 V dual output 02 AHE2812D/CH - SLV DC/DC converter, 15 W, 12 V dual output 03 AHE2812D/CH - MSTR DC/DC converter, 15 W, 12 V dual output 1.2.3 Device class designator.
9、This device class designator shall be a single letter identifying the product assurance level. All levels are defined by the requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H, K, and E) or QML Listing (Class G and D). The product assurance levels are as fo
10、llows: Device class Device performance documentation K Highest reliability class available. This level is intended for use in space applications. H Standard military quality class level. This level is intended for use in applications where non-space high reliability devices are required. G Reduced t
11、esting version of the standard military quality class. This level uses the Class H screening and In-Process Inspections with a possible limited temperature range, manufacturer specified incoming flow, and the manufacturer guarantees (but may not test) periodic and conformance inspections (Group A, B
12、, C, and D). E Designates devices which are based upon one of the other classes (K, H, or G) with exception(s) taken to the requirements of that class. These exception(s) must be specified in the device acquisition document; therefore the acquisition document should be reviewed to ensure that the ex
13、ception(s) taken will not adversely affect system performance. D Manufacturer specified quality class. Quality level is defined by the manufacturers internal, QML certified flow. This product may have a limited temperature range. Provided by IHSNot for ResaleNo reproduction or networking permitted w

44、at both outputs. For operation at 16 V dc input, derate output power by 33 percent. 5/ When operating with unbalanced loads, at least 25 percent of the load must be on the positive output to maintain regulation. 6/ Capacitive load may be any value from 0 to the maximum limit without compromising dc
45、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 p
46、rocess changes. Thereafter parameters shall be guaranteed to the limits specified in table I. 8/ An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit protection and is the condition of maximum power dissipation. 9/ Load step
47、transition time between 2 and 10 microseconds. 10/ Recovery time is measured from the initiation of the transient to where VOUT has returned to within 1 percent of VOUT at 50 percent load. 11/ Input step transition time between 2 and 10 microseconds. 12/ Turn on delay time measurement is for either
48、a step application of power at the input or the removal of a ground signal from the inhibit pin (pin 2) while power is applied to the input.
