Radiation-hardened Power-management Device Integrates Comprehensive Functionality in an Ultra-small Form Factor

July 12, 2016 by Texas Instruments

Texas Instruments (TI) (NASDAQ:TXN) today introduced the industry’s first double-data-rate (DDR) memory linear regulator for space applications.

Texas Instruments (TI) (NASDAQ:TXN) today introduced the industry’s first double-data-rate (DDR) memory linear regulator for space applications. The TPS7H3301-SP is the only DDR regulator immune to single-event effects up to 65 megaelectron volts per centimeter squared (MeV-cm2), powering space-satellite payloads including single-board computers, solid-state recorders and other memory applications.

Integrating two monolithic power field-effect transistors (FETs) for source and sink termination and an internal voltage reference, the TPS7H3301-SP is up to 50 percent smaller than a switch-mode regulator DDR solution. To see a live demonstration of the new regulator and learn about other products from TI’s leading-edge radiation-hardened portfolio, visit Booth 43 during the 2016 Institute of Electrical and Electronics Engineers (IEEE) Nuclear and Space Radiation Effects Conference (NSREC), starting today.

 

Key features and benefits:

  • Small size: At 0.16 square inches, the device is up to 50 percent smaller than a switch-mode regulator DDR solution, delivering critical weight and launch cost savings.
  • Superior radiation performance: Along with industry-leading immunity, the device withstands a total ionizing dose of up to 100 krad. Its stable termination power supply ensures that single-event effects do not impact read-and-write operations.
  • Easy design-in: Designers can pair the TPS7H3301-SP with the TPS50601-SP buck converter to create the smallest complete power solution for DDR memory. As with TI’s entire space portfolio, designers have access to a full suite of support resources, including comprehensive radiation reports, on-demand training and Simulation Program with Integrated Circuit Emphasis (SPICE) models.
  • Maximum export: The device is controlled under U.S. Department of Commerce Export Control Classification Number (ECCN) EAR99.
  • Tools and support to jump-start designs

Designers can reduce development time and quickly complete worst-case circuit analysis by downloading a full-capability linear regulator SPICE model.

 

Package, availability and pricing

The TPS7H3301-SP is available now in a 16-pin dual-ceramic flat package that is Qualified Manufacturer List (QML) Class V and 100 krad (silicon) radiation hardness assurance (RHA) qualified (5962R1422801VXC).
