Microchip rad-hard power management device suited to LEO space applications
Article By : Microchip Technology Inc.
Microchip's first COTS rad-tolerant power, the MIC69303RT 3A LDO voltage regulator, is targeted at LEO and other space applications.
The commercialization of the Low-Earth Orbit (LEO) region is transforming space exploration and satellite communication at roughly 1,200 miles above Earth. For satellites to successfully operate and reach their destination it is essential to select components that can withstand the harsh space environment.
Microchip Technology Inc.在其现有的耐辐射投资组合上建造，已使用MIC69303RT 3A低落（LDO）电压调节器推出了其首个商业式货架（COTS）耐受耐耐力设备。新的高电流低压MIC69303RT是针对LEO和其他空间应用的电源管理解决方案。该设备可用于塑料和密封陶瓷的原型采样，以支持任务的要求。
The MIC69303RT is based on proven COTS devices making it easier to conduct preliminary evaluation and early development. Operating from a single low voltage supply of 1.65V to 5.5V, the device can supply output voltages as low as 0.5V at high currents, offering high precision and ultra-low dropout voltages of 500mV under extreme conditions. The MIC69303RT is a companion power source solution for Microchip’s radiation-tolerant space-qualified microcontrollers such as the SAM71Q21RT and PolarFire FPGAs including the RTPF500TLS.
“ MIC69303RT是Microchip的第一台RAD耐力电力管理设备，配备密封陶瓷包装，锁定免疫力和50 krad的总剂量稳健性，” Microchip Aerospace和国防业务部门副总裁Bob Vampola说。“ Microchip在全面的投资组合中拥有超过60年的太空飞行遗产，使客户可以选择旨在共同努力并加速其设计过程的产品。”
“This COTS rad-tolerant power management solution enables new design possibilities in space applications,” said Keith Pazul, director of marketing for Microchip’s analog power and interface business unit. “Customers can design their space system with confidence by selecting the COTS MIC69303RT space-qualified part to power Microchip space-qualified MCUs and FPGAs.”
Designed for harsh aerospace applications, the MIC69303RT is operational in temperature ranges from -55°C to 125°C. It is offered in 8-pin and 10-pin package configurations with radiation tolerance up to 50 Krad. The low noise of the output is critical to sensitive RF circuits, post regulation of switching power supplies and industrial power applications.
The MIC69303RT device is the newest space-qualified product by Microchip and is manufactured in compliance with the following MIL Class Q or Class V requirements: screening testing, qualification testing and TCI/QCI specifications. The plastic MIC69303RT is compliant with high reliability plastic quality flow derived from AEC-Q100 automotive requirements with specific additional tests necessary for space applications.
The MIC69303RT Plastic Evaluation Board is designed to evaluate the performance of the plastic engineering IC version for the MIC69303RT. The 4-layer PCB allows the user to easily change and measure the electric parameters of the device at different input and output conditions.
