STMicroelectronics LEOPOL1
The LEOPOL1 is a single-phase, step-down monolithic switching regulator with highprecision 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.
