Microchip Technology Inc. (Nasdaq: MCHP) has eliminated the cost, complexity and customization challenges of these hybrid solutions by offering a discrete-component-based, space-grade DC-DC power converter family that now includes 28V-input, 50-watt (W) radiation-tolerant options. “Our latest 28V-input SA50-28 products greatly simplify and accelerate system development,” said Leon Gross, vice president of Microchip’s discrete product business unit. “They are easier to customize than alternative space-grade power converters so they can meet specific voltage, current and other needs. Customers gain flexibility while reducing the size, cost and complexity of their space system designs.” Microchip’s SA50-28 family is the industry’s only off-the-shelf, 28V-input, radiation-tolerant power converter offering that is based on discrete components with surface-mount construction and non-hybrid assembly processes. Delivering more capabilities than alternative off-the-shelf, space-grade power converters, a single SA50-28 device with customized parameters eliminates the volume, weight and complexity problems of using hybrid solutions with their multiple devices and surrounding circuitry. Microchip’s comprehensive SA50-28 product line is a 20V- to 40V-input, 50W family with nine standard outputs of 3.3V, 5V, 12V, 15V and 28V in single- and triple-output configurations. The devices can be tailored to a system’s exacting power needs in a relatively short time with minimal additional costs as compared to hybrid-style power converter products. Other features include high efficiency, low output noise, output inhibit control, overcurrent protection, external synchronization and full-rated power operation through −55°C to +85°C with linear derating to +125°C. The SA50-28 family is part of Microchip’s growing line of standard non-hybrid, space-grade power converters that enable designers to use commercially available, off-the-shelf components whose circuitry has a proven spaceflight heritage. The products join the radiation-har...
