고정 온타임 PFM(펄스 주파수 변조) 제어 DC-DC 컨버터에 적합한 과전류 보호 방법을 제안합니다. 이는 인덕터 하단 전류 제한을 기반으로 하며 동기 정류기 전류를 모니터링하고 메인 스위치의 OFF 위상을 미리 결정된 한계까지 감소할 때까지 확장하여 구현되며 단락이 발생하는 경우에도 출력 전류를 적절하게 제한할 수 있습니다. 제안된 과전류 보호 기능을 갖춘 고정 온타임 PFM DC-DC 컨버터는 CMOS IC에서 설계 및 제작되었습니다. 시뮬레이션과 측정을 통해 전류 제한 동작을 검증했습니다.

Abstract: An over current protection method suitable for Fixed ON-time PFM (Pulse Frequency Modulation) Control DC-DC converters is proposed. It is based on inductor bottom current limiting, realized by monitoring the synchronous rectifier current and extending the OFF-phase of the main switch until it decreases to a predetermined limit, and can properly limit the output current even in case of short circuit. A Fixed ON-time PFM DC-DC converter with the proposed over current protection was designed and fabricated in CMOS IC. Its current limiting operation was verified with simulations and measurements.
