About this document
Enhancing LM2575 with LM2576 Circuit by Ingvarsk is a document available to read on EtoBox.
The document discusses modifying a simple switch-mode controller (LM2575) to increase its output current by using it to drive an external p-channel MOSFET. The LM2575 switches the MOSFET on and off, allowing it to handle higher output currents than the LM2575 alone. However, this modification removes short-circuit and overtemperature protections. Faster transistors like the BS170 should be used to improve switching speeds. The inductor and capacitors must also be suitable for the higher currents and frequen
