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
available, a choice of radiation hardness assurance levels are reflected in the PIN.

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 type(s) identify the circuit function as follows:
Device type
01
Generic number
GH2803R3S/CK
Circuit function
DC/DC converter, 50 W, +3.3 V Output
1.2.3 Device class designator. 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 follows:
Device class
K
H
G
Device performance documentation
Highest reliability class available. This level is intended for use in space
applications.
Standard military quality class level. This level is intended for use in applications
where non-space high reliability devices are required.
Reduced testing 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, C, and D).
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 exception(s) taken will not adversely affect
system performance.
Manufacturer specified quality class. Quality level is defined by the manufacturers
internal, QML certified flow. This product may have a limited temperature range.

of this drawing to the extent specified herein. Unless otherwise specified, the issues of these documents are those cited in the
solicitation or contract.
DEPARTMENT OF DEFENSE SPECIFICATION
MIL-PRF-38534 - Hybrid Microcircuits, General Specification for.
DEPARTMENT OF DEFENSE STANDARDS
MIL-STD-883 - Test Method Standard Microcircuits.
MIL-STD-1835 - Interface Standard for Electronic Component Case Outlines.
DEPARTMENT OF DEFENSE HANDBOOKS

Document Order Desk, 700 Robbins Avenue, Building 4D, Philadelphia, PA 19111-5094.)
2.2 Order of precedence. In the event of a conflict between the text of this drawing and the references cited herein, the text of
this drawing takes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a
specific exemption has been obtained.
3. REQUIREMENTS
3.1 Item requirements. The individual item performance requirements for device classes D, E, G, H, and K shall be in
accordance with MIL-PRF-38534. Compliance with MIL-PRF-38534 may include the performance of all tests herein or as
designated in the device manufacturer's Quality Management (QM) plan or as designated for the applicable device class.
Therefore, the tests and inspections herein may not be performed for the applicable device class (see MIL-PRF-38534). The
manufacturer may eliminate, modify or optimize the tests and inspections herein, however the performance requirements as
defined in MIL-PRF-38534 shall be met for the applicable device class. In addition, the modification in the QM plan shall not
affect the form, fit, or function of the device for the applicable device class.

Stresses above the absolute maximum ratings may cause permanent damage to the device. Extended operation at the
maximum levels may degrade performance and affect reliability.
Derate output power linearly above case temperature +125C to 0 at +135C.
Limit represent 80 percent of total rated output current. To achieve rated output power, the remaining 20 percent of the total
rated output current must be provided by the other output.
For operation at temperatures between +85C and +125C, derate the maximum input voltage linearly from 60 V dc to 40 V
dc and the maximum output power linearly from 100 percent to 75 percent.
