The commercialization of the Low-Earth Orbit (LEO) area is reworking house exploration and satellite tv for pc communication at roughly 1,200 miles above Earth. For satellites to efficiently function and attain their vacation spot, it’s important to pick out parts that may stand up to the cruel house atmosphere.
Constructing on its current radiation-tolerant portfolio, Microchip Expertise Inc. (Nasdaq: MCHP) declares as we speak the introduction of its first commercial-off-the-shelf (COTS) rad-tolerant energy system with the MIC69303RT 3A Low-Dropout (LDO) Voltage Regulator. The brand new high-current, low-voltage MIC69303RT is an influence administration resolution concentrating on LEO and different house purposes. The system is out there for prototype sampling in each plastic and airtight ceramic to assist the necessities of the mission.
The MIC69303RT is predicated on confirmed COTS units, making it simpler to conduct preliminary analysis and early growth. Working from a single low-voltage provide of 1.65 to five.5 volts, the system can provide output voltages as little as 0.5V at excessive currents, providing high-precision and ultra-low dropout voltages of 500 mV beneath excessive situations. The MIC69303RT is a companion energy supply resolution for Microchip’s radiation-tolerant space-qualified microcontrollers such because the SAM71Q21RT and PolarFire FPGAs together with the RTPF500TLS.
“The MIC69303RT is Microchip’s first rad-tolerant energy administration system with a airtight ceramic package deal, latch-up immunity and 50 Krad whole dose robustness,” mentioned Bob Vampola, vp of Microchip’s aerospace and protection enterprise unit. “Microchip has over 60 years of house flight heritage in a complete portfolio that permits clients to decide on merchandise designed to work collectively and speed up their design processes.”
“This COTS rad-tolerant energy administration resolution permits new design potentialities in house purposes,” mentioned Keith Pazul, director of promoting for Microchip’s analog energy and interface enterprise unit. “Prospects can design their house system with confidence by deciding on the COTS MIC69303RT space-qualified half to energy Microchip space-qualified MCUs and FPGAs.”
Designed for harsh aerospace purposes, the MIC69303RT is operational in temperature ranges from -55 C to +125 C. It’s supplied in 8-pin and 10-pin package deal configurations with radiation tolerance as much as 50 Krad. The low noise of the output is crucial to delicate RF circuits, put up regulation of switching energy provides and industrial energy purposes.
The MIC69303RT system is the most recent space-qualified product by Microchip and is manufactured in compliance with the next MIL Class Q or Class V necessities: screening testing, qualification testing and TCI/QCI specs. The plastic MIC69303RT is compliant with high-reliability plastic high quality move derived from AEC-Q100 automotive necessities with particular further exams obligatory for house purposes.

Radiation shielding: MAPbI3/epoxy composites exhibit superior performance
Changchun, China (SPX) Dec 14, 2022
Because the speedy growth of aerospace and nuclear industries, increased necessities are raised for the service lifetime of detectors and the security of workers. Gamma ray with extraordinarily brief wavelength and powerful penetration would trigger the intense injury to the detectors and workers. Subsequently, you will need to develop gamma ray shielding supplies with excellent radiation shielding efficiency.
Nevertheless, the normal Lead shielding materials can not appropriate for additional business purposes because of … read more
