Space system developers can rapidly develop prototypes and final designs for their power management system using a radiation-tolerant device based on a commercial plastic-encapsulated device
The commercialization of the LEO (Low Earth Orbit) region is transforming space exploration and satellite communication some 2.000 km from Earth. In order for the satellites to function correctly and reach their destination, it is essential to select components capable of withstanding the adverse environment of space. Building on its portfolio of radiation-tolerant products, Microchip Technology Inc. today announces its first commercial-grade radiation-tolerant (COTS) power device: the MIC69303RT, a 3A LDO voltage regulator. The new MIC69303RT for High Current and High Voltage is a power management solution for LEO and other space applications. This device is available for prototype sampling in plastic-encapsulated and ceramic-sealed versions to meet mission requirements.
The MIC69303RT is based on proven commercial devices, making it easy to pre-test and develop. Powered by a single 1,65V to 5,5V low-voltage supply, the device can supply output voltages starting at 0,5V with high currents, as well as high accuracy and ultra-low dropout voltages 500 mV for extreme conditions. The MIC69303RT is an auxiliary power solution for Microchip's space-capable and radiation-tolerant microcontrollers such as the SAM71Q21RT and PolarFire FPGAs.® like RTPF500TLS.
“The MIC69303RT is Microchip's first radiation-tolerant power management device with a hermetic ceramic package, block immunity, and robustness with a total dose of 50 Krad,” said Bob Vampola, vice president of the Aerospace and Business Unit. defense from Microchip. "Microchip has more than 60 years of spaceflight experience and a comprehensive portfolio that allows customers to choose products designed to work together and speed up their design processes."
“This commercial radiation-tolerant power management solution opens up new design possibilities in space applications,” said Keith Pazul, director of marketing for Microchip's analog power and interfaces business unit. "Customers can design their space system with confidence by selecting the commercial space-qualified device MIC69303RT to power Microchip's space-qualified microcontrollers and FPGAs."
Designed for harsh aerospace applications, the MIC69303RT can work in a temperature range of -55°C to +125°C. It is offered in 8-pin and 10-pin configuration packages with radiation tolerance up to 50 Krad. Low output noise is a must in sensitive RF circuitry, post-regulation switching power supplies, and industrial power applications.
The MIC69303RT device is Microchip's newest space-qualified product and is manufactured to meet the following MIL Class Q or Class V requirements: shielding tests, type approval tests, and TCI/QCI specifications. The plastic-encapsulated MIC69303RT offers the high-reliability plastic grade derived from AEC-Q100 automotive requirements with the additional testing necessary for space applications.
