Radiation-tolerant power-package power management, A new class of small satellites that will offer services like high-speed Internet connections to hundreds of millions of people in societies, governments, and commercial enterprises worldwide will be powered and supported by ICs. Mega-constellation networks will be built using fleets of hundreds of tiny satellites to bring broadband Internet connections from low Earth orbit to every corner of the world, even remote locations lacking wireless connectivity.
Smallsat mega-constellations enable high-resolution Earth observation imaging for tracking marine, air, and land assets in addition to delivering global broadband Internet access.
Switching regulators, PWM controllers, and Gallium Nitride FET drivers are all parts of Renesas’ radiation-tolerant plastic package power management IC technology, which offers the best radiation performance and price that new space customers need for profiles in low Earth orbit.Rays and electromagnetic waves are both considered wave radiation for these reasons.
In general, wave radiation contains characteristics including reflection, absorption, refraction, and diffusion that are similar to those of optics. The wavelengths of space radiation, however, go well beyond and beyond the range of visible light. Radiation below visibility includes microwaves and radio frequencies.
The Global Radiation tolerant power supplies Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The commercialization of the Low-Earth Orbit region, located about 1,200 miles above the Earth, is revolutionising satellite communication and space exploration, as demonstrated by Microchip’s launch of Radiation-Tolerant Power.
It is crucial to choose components that can resist the harsh space environment for satellites in order for them to function properly and reach their destination. The MIC69303RT 3A Low-Dropout Voltage Regulator, part of Microchip Technology Inc.’s expanding radiation-tolerant portfolio, is the company’s first commercially available rad-tolerant power device.
Targeting LEO and other space applications, the new high-current, low-voltage MIC69303RT is a power management system. To satisfy the needs of the mission, the device is available for prototype sampling in both plastic and hermetic ceramic. The MIC69303RT is built on tested COTS devices, making early development and preliminary testing simpler.
The device can produce output voltages as low as 0.5V at high currents and offers high-precision and ultra-low dropout values of 500 mV under challenging circumstances when powered by a single low-voltage source ranging from 1.65 to 5.5 volts. For Microchip’s radiation-tolerant space-qualified microcontrollers like the SAM71Q21RT and PolarFire FPGAs like the RTPF500TLS, the MIC69303RT provides a partner power source solution.
