Microchip Technology Inc. (Nasdaq: MCHP) has designed inflexible hybrid-style converters for improving design flexibility while reducing system size, budget involved, and development time.
As per the firm’s announcement, this technology comes in handy, especially for Space system designers who cannot easily support non-standard voltages or add functions with traditional hybrid-style power converters.
According to the firm’s reports, these inflexible hybrid-style converters offer out a discrete-component-based, space-grade DC-DC power converter family that now comprises a 28V-input, 50-watt (W) radiation-tolerant options.
Leon Gross, vice president of Microchip’s discrete product business unit stated: “Our latest 28V-input SA50-28 products greatly simplify and accelerate system development. 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.”
As per Microchip’s announcement, 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.
The firm’s report also added that these inflexible hybrid-style converters will be delivering more capabilities than alternative off-the-shelf, space-grade power converters, and with a single SA50-28 device with the customized parameters curbs down the volume, weight, and complexity problems of utilization of the 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.
Additionally, as per the interim reports from Microchip, the salient features of these hybrid-style converters 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-hardened SA50- 120 power converter family, introduced in February 2021 that reduces risk and development time for qualified space systems by allowing designers to start with proven commercially available off the shelf technology in ceramic or plastic packages and quickly scaling up development using lower screening levels than traditional Qualified Manufacturers List (QML) requirements.
