Co-developed with CERN, the EPCS4001 offers PWM operation up to 3 MHz. It integrates bias regulators (12&nbsp;V &amp; 5&nbsp;V), UVLO, thermal protection, and Power-Good telemetry. It is optimized to drive EPC&nbsp;GaN power stages like the EPC7011L7 family for a turnkey point-of-load architecture. The EPCSC401 features a Pre-optimized layout minimizing loop inductance. It supports cored\/coreless inductors and conduction cooling and has verified thermal design for space-like environments. The modular controller + GaN stage solution enables compact point-of-load converters for satellites, payloads, defense, and high-energy physics systems. The combination offers turnkey integration via reference board, accelerating development and reducing risks in space-grade applications.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/news\/1752230106695_638878269095713191.png\" class=\"imageload removeImageattr fr-dib\" width=\"711\" height=\"378\" ><\/p>\n<p>EPC Space packages its GaN devices in ceramic modules and adapters designed for high-reliability space deployment.
