APPLICATION NOTE
HOW TO HANDLE SHORT CIRCUIT CONDITIONS
WITH ST’s ADVANCED PWM CONTROLLERS
by Claudio Adragna & Giuseppe Gattavari




Purpose of this note is to provide some advice on how to manage a short circuit condition for a switching
converter controlled by ST's advanced PWM controllers L5991 and L5993.
After a quick review of merits and limits of the current limitation functionality embedded in these IC's, a
simple circuit will be given that allows to fulfill des
