IR Introduces LSO Series of Feature-Rich Radiation Hardened Low-Voltage DC-DC Converters for Satellite Power Systems
EL SEGUNDO, Calif.--(BUSINESS WIRE)-- International Rectifier, IR® (NYS: IRF) , a world leader in power management technology, today introduced the LSO Series of feature-rich radiation-hardened (RAD-Hard) low-voltage, single- and dual-output DC-DC converter modules for satellite power systems requiring up to 15 years or more of mission life.
The LSO Series delivers isolated output voltages from 1.5V to 15.0V with typical efficiency performance up to 81 percent and features MIL-STD-461C CE03-compliant internal EMI filter. The new 30W modules offer unique functional features that include latch-off output over-voltage protection (OVP) to help prevent damage to the high value digital and analog loads as a result of an over-voltage condition. An adjustable OVP threshold voltage, input current telemetry, and under-voltage lockout (UVLO) with latching mode options are also included.
"Based on IR's proven technology, the LSO Series of low-voltage, RAD-Hard DC-DC converters are intended for a wide range of digital and analog satellite power system designs. With built-in OV protection and input current telemetry circuitry, these converter modules help simplify system redundancy design, improve system reliability and reduce overall program costs," said Tiva Bussarakons, Marketing Director, IR's HiRel Business Unit.
Available in a 3.5" x 2.5" x 0.475" standard form factor with a low weight of < 125 grams, the converters are characterized with total ionizing dose (TID) of greater than 100K Rad(Si), and single event effect (SEE) linear energy transfer (LET) of heavy ions greater than 82 MeV.cm2 /mg.
Other key features include 18V to 40V input range, magnetically coupled feedback to insure optimum cross-regulation when the loads are unbalanced, remote sense compensation for single output models, and adjustable output voltage.
