Space DC-DC Converters

 

IR HiRel offers a large portfolio of space-level radiation-hardened (rad hard) hermetic, hybrid DC-DC converters and PCB open frame and enclosed power supplies. The hermetic hybrid DC-DC converters are qualified to MIL-PRF-38534 Class K and available as Standard Microcircuit Drawings (SMDs). Design practices follow military standards and de-ratings. Our space-level DC-DC converter offering includes:

High Reliability Hermetic Hybrid DC-DC Converters

  • General purpose and application-specific DC-DC converters, including MIL-STD-461 filters
  • Standard and advanced functionality and protections
  • License-free exportable (EAR-99) rad hard products
  • Radiation Hardened Assurance (RHA) plan
  • Immunity to TID, SEE, neutron and prompt dose radiation environments in space

High reliability PCB/PWB DC-DC converters (open frame or enclosed)

IR HiRel’s rad hard power supply units (PSU) deliver high efficiency and excellent overall performance, while supporting

  • High current
  • High power
  • Complex designs
  • Advanced topology and magnetic design

We deliver a range of standard platforms based on a general design philosophy which can be tailored to the customer’s program requirements. Fully customized designs are also supported.

Quality Conformance Testing

Unlike standard commercial products, HiRel products must be submitted to various levels of quality conformance testing to ensure that the products are capable of performing to specifications in the often harsh environments of military and space applications. Both the United States and European community have each developed specifications that detail the sequence of quality conformance testing.

In the United States, the Defense Logistics Agency (DLA) is the controlling agency and has issued specifications that govern the quality conformance testing sequence performed on semiconductor devices and hybrid modules, namely MIL-PRF-19500/MIL-STD-750, MIL-PRF-38534/MIL-STD-883 and MIL-PRF-38535/MIL-STD-883.

MIL-PRF-38534/MIL-STD-883 are the controlling specifications for power hybrids. MIL-STD-883 directs hybrids te be manufactured to class H or class K.

International Rectifier HiRel Products Group manufactures and tests hermetic products to one of three distinct quality conformance levels: (1) commercial hermetic, (2) source control drawing (SCD), or (3) MIL-PRF-38534, MIL-PRF-38535 qualified.

Screening and Quality Conformance Inspection Requirements

QPL Listing - DC-DC

Glossary

Class H: Class H is the standard military quality level provided in MIL-PRF-38534, General Specification for Hybrid Microcircuits. It is intended for space applications.

Level B: Class level B defines the screening requirements for high reliability military applications as specified in MIL-STD-883 and is intended for use in class H products.

Level S: Class level S defines the screening requirements for high reliability space applications as specified in MIL-STD-883 and is intended for use in class K products.

JAN: JAN (Joint Army Navy) is the prefix assigned by the DLA to designate devices on the DLA qualified parts list.

JANTX: Military screening level as specified in MIL-PRF-19500 for a DLA qualified device.

JANTXV: Military with visual inspection screening level as specified in MIL-PRF-19500 for a DLA qualified device.

JANS: Space level screening as specified in MIL-PRF-19500 for a DLA qualified device.
