International Rectifier, a leader in power management technology, introduced the radiation-hardened ML Series dual output DC-DC power converter platform designed for RF communication equipment such as low noise amplifiers (LNA), receivers and frequency converters used onboard satellites. IR's ML Series features output sequencing typically required by RF-circuitries and isolated telemetry/telecommand for compliant satellite telemetry/telecommand systems without the need for additional components. Other key design features include integrated input EMI filter compliant to most major satellite power buses, radiation hardness of 100 Krad (TID) and 82MeV?cm2/mg (SEE) and output voltage accuracy to 2% at worst case end of life. The platform also offers extremely low output ripple/noise of less than 0.5Vrms (50Hz to 50MHz), excellent input to outputs CS rejection greater than 90dB, and input under-voltage lock-out (UVLO) with optional latching or with automatic restart. "The ML series is a full-feature turn-key electronic power conditioner (EPC). Ready for system use without the need for additional engineering resources, this new platform significantly reduces overall program cost and design effort for satellite manufacturers," said Tiva Bussarakons, Marketing Director, IR's HiRel Business Unit. Availability and Pricing Pricing for the ML Series begins at $22,000 each in low-unit quantities. Production orders are available immediately. Prices are subject to change. This product is subject to U.S. export control laws and regulations, including but not limited to the US International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR).
