Abstract：In viewof the increasing integration of spacesystemsand the demandof larger integratedcircuits for highpower density and miniaturized radiation-hardened point of load（POL）power suply，a design scheme for the high power density dual-circuit radiation-hardened POL power supplyis proposed.The circuit design， components selection，structural and technological design are described separately.Through simulations aualysis， analog experiments，sample testing and evaluation tests，the ratioualityof the design is verified.The power density of radiation-hardenedPOL power supplysignificantly exceeds thatof traditional power supply.In the caseof the limited areaof the single machineand the integration in spacesystem，itcan providea miniaturizedand lightweight high-power radiation-hardened POL power supply platform.

Keywords：high-powerdensity； radiation-hardened POL powersupply； miniaturization;high reliability
