Kaedah perlindungan arus lebih yang sesuai untuk penukar DC-DC Kawalan PFM ON-time (Pulse Frequency Modulation) Tetap dicadangkan. Ia berdasarkan pengehadan arus bawah induktor, direalisasikan dengan memantau arus penerus segerak dan memanjangkan fasa OFF suis utama sehingga ia berkurangan kepada had yang telah ditetapkan, dan boleh mengehadkan arus keluaran dengan betul walaupun dalam kes litar pintas. Penukar PFM DC-DC ON-time tetap dengan perlindungan arus lebih yang dicadangkan telah direka bentuk dan direka dalam CMOS IC. Operasi pengehad semasanya telah disahkan dengan simulasi dan pengukuran.

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.
