Current Limiter Circuits

13.8 Volt 20PSU: This is a Regulated DC power supply with short circuit protection and with current limiter.

9 Volt 2PSU: A simple 9 Volt 2 amp supply using a single IC regulator.

Circuit provides hiccup current limiting: 06/26/03  EDN-Design Ideas / Current-limit protection is an essential feature for power-supply systems. The three major types of current-limit-protection mechanisms are constant, foldback, and hiccup. Hiccup current limit performs the best of the three types; however, the implementation is rather complex. In this scheme, upon detection of an overcurrent event, the whole power supply shuts down for an interval before it tri....

Eliminate Latching Current Limit In Power Supplies : 08/05/02 Electronic Design - Ideas for Design / Most modern power-supply control ICs offer built-in overcurrent or short-circuit protection. While some overcurrent-protection schemes are latching, others are nonlatching. When the overcurrent trip level is reached in a latching controller, the...
