IR Introduces Highly Reliable DLA-certified RAD-Hard Ultra-Low Dropout DC-DC Voltage Regulators for Space Applications
EL SEGUNDO, Calif. --(Business Wire)--
International Rectifier, IR® (NYSE: IRF), a world leader in
power management technology, today introduced a series of high current,
ultra-low dropout (ULDO) RAD-Hard hybrid linear voltage regulators
available in Standard Microcircuit Drawings (SMD) for space applications
including satellites and launch vehicles.
The new Defense Logistics Agency (DLA), Land and Maritime certified
voltage regulators are also included in IR's Radiation Hardness
Assurance (RHA) program certified by DLA Land and Maritime division
(formerly DSCC) that guarantees the devices' radiation performance down
to the component level.
The space level screened devices, designed for point-of-load and post
DC-DC power conversion, offer a low dropout voltage of only 0.4 V at
full 3 A load. They are available in two industry standard package
styles, a 5-pins MO-078AA and an 8-pins flat pack, each with multiple
lead bend options. The new regulators feature a Silicon On Insulator
(SOI) CMOS Regulator IC, latch-up and SEU immunity with LET of 84 MeV.cm2/mg,
as well as outstanding TID rating of 300 Krad(Si) and ELDRS testing in
excess of 100 Krad(Si) with negligible effect on regulation tolerance.
In addition, the devices provide fast transient response, timed
latch-off over-current protection and internal thermal protection, and
on/off control via shutdown pin.
"In addition to offering DLA-certification, these voltage regulators
using a standard microcircuit drawing (SMD) part number are included in
IR's RHA program to offer customers a highly reliable, government
approved solution. The new devices augment IR's space hybrid product
line and complement our DC-DC converters to provide a one-stop power
management solution supplier for the space community," said Tiva
Bussarakons, Marketing Director for IR's HiRel DC-DC Converter Products.
Design analyses including worst case (WCA), electrical stress, thermal,
stability with respect to additional output capacitors, and DFMEA are
available at no-charge for standard models.
