A hot-swap protection control chip is designed,which realized the protection of over-current and short circuit in DC boost circuit output. The work principle and implementation model of DC boost circuit and the hot-swap protection circuit are analyzed. The circuit,the parameters design,the selection process and actual work switching waveforms are introduced in detail,and the design examples are given. Experiments show that using hot-swap protection control chip can effectively avoid the inherent defects of the conventional DC boost circuit in overcurrent short circuit. It improved the reliability of power supply.
