Fully integrated Point-of-Load converter modules for space
The new designs are part of the TD5 Series, a family of point-of-load DC-DC converter modules engineered specifically for harsh radiation environments which require low voltages and tight regulation.
The modules cover an input voltage range of 4.6 to 6.0V and are available in 2, 6, and 10 A output surface-mount options. Where conventionally a designer implementing regulated voltage conversion for a space application would be required to choose, specify, purchase and inventory up to a dozen space-qualified passive components to achieve a complete solution, the module simplifies the design and implementation and increases the reliability of the system.
The TD5 Series uses the Teledyne/PSemi PE9915X family of radiation tolerant synchronous buck regulators to provide high power density, fast transient response, and up to 90% efficiency. These have a Total Ionizing Dose (TID) of 100krad (Si) and Single Event Effects (SEE) over 90 MeV-cm2/mg.
“The high radiation tolerance of the TD5 Series is powered by the PSemi patented UltraCMOS® technology,” said Hector Rivera Integrated Solutions Product Line Manager for Teledyne e2v HiRel. “The product design provides a plug and play option for the designers of modern space digital electronics, which is especially important as digital power rail tolerances continue to shrink.”
The TD5 Series includes power good signal and shutdown pin for power sequencing and is rated for -40° C to +85° C.
“Space systems have increased the use of digital processing components that require low-voltage, tightly regulated point of load converters,” said Mont Taylor, VP of Business Development for Teledyne e2v HiRel. “Bottom line, this new module family greatly simplifies the job of space designers. This new capability showcases our growing footprint in microelectronics design and production, and is owed in part to the decades of experience we have leveraged working with our Teledyne sister company, Teledyne Advanced Electronics Systems (AES).”
Engineering units of the TD5 series are available today.
