\"EPC<\/p>\n

EPC Space<\/strong> announces the release of the EPCS4001, a radiation-hardened, high-frequency buck DC-DC PWM converter controller optimized for space and high-energy physics applications. In tandem with the EPCS4001, EPC Space also introduces the EPCSC401 reference design, offering engineers a complete, tested, and ready-to-deploy solution. The EPCS4001 is a rad-hard CMOS ASIC, co-developed with The European Organization for Nuclear Research, known as CERN, tailored specifically for use with EPC\u2019s GaN-based Rad Hard power stage the EPC7011L7 family. This two-component solution provides a robust and flexible point-of-load converter architecture that excels in extreme environments.<\/p>\n

Key Features of the EPCS4001:<\/p>\n

    \n
  • Wide Input Voltage Range: 18 V to 50 V input, with an adjustable output centered at 12 V<\/li>\n
  • High Switching Frequency: Adjustable from 0.5 MHz to 3 MHz, enabling use of compact inductors from 200\u2013500 nH.<\/li>\n
  • Integrated Bias Regulators: On-chip 12 V and 5 V linear regulators eliminate the need for external bias circuitry.<\/li>\n
  • Protection & Telemetry: Built-in under-voltage lockout (UVLO), over-temperature protection, and Power Good signal for fault monitoring.<\/li>\n
  • Radiation and Magnetic Tolerance: Operates reliably in environments with very high radiation. The controller has been designed for operation in a strong magnetic field in excess of 40,000 Gauss.<\/li>\n
  • Fully Compatible with EPC GaN Power Stages: Designed to pair with the EPC7011L7 family, enabling radiation-hardened power conversion in compact form factors.<\/li>\n<\/ul>\n

    EPCSC401 Reference Design \u2013 Turnkey Performance<\/strong><\/p>\n

    To support rapid design-in, EPC Space has released the EPCSC401 reference design, a 48 V-to-12 V buck converter that demonstrates the full capabilities of the EPCS4001 and EPC7011L7 family in a compact layout. It features:<\/p>\n

      \n
    • Pre-optimized PCB layout for minimal loop inductance and maximum efficiency.<\/li>\n
    • Compatibility with both cored and coreless inductors, allowing designers to tailor magnetic components for application-specific needs, including high magnetic field environments.<\/li>\n
    • Verified thermal performance with conduction cooling and integrated heatsinking for space-like conditions.<\/li>\n<\/ul>\n

      <\/p>\n

      \u201cOur customers asked for a simplified path to integrate GaN-based, radiation-hardened DC-DC conversion into their systems, and the EPCS4001 with the EPCSC401 reference design delivers exactly that<\/em>,\u201d said Maurizio Salato<\/strong>, VP of Engineering at EPC Space<\/strong>.<\/p>\n

      Applications<\/strong><\/p>\n

        \n
      • Spacecraft power systems<\/li>\n
      • High Energy Physics instrumentation<\/li>\n
      • Radiation-tolerant point-of-load converters<\/li>\n
      • Defense and aerospace systems requiring high efficiency and compact size<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
