Designed to support a range of space applications from 5G communications to IoT and cube satellites, these power converters offer flexibility with nine variants and robust integration capabilities with existing technologies.Â
Microchip Technology announced the launch of a new family of Radiation-Tolerant (RT) LE50 28 isolated DC-DC 50W power converters to address the growing needs of the Low-Earth Orbit (LEO) market. This market is expanding as the private and public sectors engage in activities ranging from 5G communication to cube satellites and IoT applications. The LE50 28 power converters come in nine variants with single and triple outputs from 3.3V to 28V, designed to meet the MIL-STD 461 standard.
The key features include:
- Converters can be paralleled up to four units for a total output of 200 watts.
- Suitable for various space applications due to enhanced adaptability.
- Offer multiple electrical connection and mounting options.
- Can handle a total ionising dose of 50 Krad.
- Feature single event effects latch up the immunity of 37 MeV·cm²/mg.
These power converters are complemented by an EMI filter that aids in design customization and scalability, allowing users to select from one or three outputs depending on their voltage requirements. These power converters are compatible with the company’s PolarFire FPGAs, microcontrollers, and LX7720 RT motor control sensors, facilitating integration into complete electrical system solutions. This compatibility is critical in reducing development time for systems operating within 28V bus environments.
The series is distinguished by its manufacturing process, which uses both surface-mount and thru-hole components, enabling quicker market entry and reducing supply chain risks. The company continues to expand its space-grade component offerings, including FPGAs, power devices, memory products, communication interfaces, oscillators, microprocessors, and microcontrollers. These components are available across different qualification levels, including the largest qualified plastic portfolio for space applications.
Leon Gross, Vice President of Microchip’s Discrete Products Group, emphasised that these new devices are designed to operate under the severe conditions of space and LEO environments, providing the dependable and cost-effective solutions customers expect from Microchip.
