Two common hot-swappable surge current control schemes

2021-12-17

In the usual design and development work, engineers often use hot-swappable surge current control circuits for filtering and charging current limitation. In view of the design requirements, it is also very important to reasonably choose the control scheme of the hot-swappable surge circuit. In todays article, we will show two common hot-swappable surge current control solutions for new engineers who have just started to work on power supply design. Lets take a look.
