製品概要
概要
The LEOPOL1 is a single-phase, step-down monolithic switching regulator with high-precision internal voltage reference and integrated power MOSFETs for synchronous conversion able to provide, at ground level (no single effect events), up to 7 A with up to 12-volt power supply, and up to 5 A from a 5.5 volt supply in a radiative environment up to 62 MeV.cm²/mg.
The LEOPOL1 can operate over a large temperature range of -40 °C to +125 °C. Designed using a BCD Silicon-On-Insulator (SOI) technology, it features an intrinsic radiation hardness, further enhanced through hardening by design, optimized to meet the radiation hardness required for Low Earth Orbit space crafts at an effective cost. Its PowerSO-36 package features a slug-down pad allowing a very low thermal resistance for a superior dissipation including in the absence of convection. It uses golden bonding and NiPdAl-lead-finishing to prevent whiskers. It complies with ASTM-E-595 and ESCC-Q-ST-70-02C outgassing standards for parts to be used in a vacuum.
The LEOPOL1 is compliant with the ST LEO generic specification, for space-ready rad-hard plastic products. This AEC-Q100 based specification offers radiation hardness and the capability to support large quantities, together with a trade-off optimized for LEO space crafts between quality assurance and cost of ownership (details on the ST LEO generic specification can be found in TN1432).
