| Abstract: | 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, tbe 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. |
