Integrating two monolithic power FETs for source and sink termination and an internal voltage reference, the TPS7H3301-SP measures 0.16 square inches. This is up to 50% smaller than a switch-mode regulator DDR solution, delivering critical weight and launch cost savings.
Along with industry-leading immunity, the device withstands a total ionising dose of up to 100krad. Its stable termination power supply ensures that single-event effects do not impact read-and-write operations.
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 SPICE models.
The TPS7H3301-SP is available now in a 16-pin dual-ceramic flat package that is Qualified Manufacturer List (QML) Class V and 100krad (silicon) Radiation Hardness Assurance (RHA) qualified (5962R1422801VXC).
The device is controlled under U.S. Department of Commerce Export Control Classification Number (ECCN) EAR99.
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.
