Switch Mode Power Supply Current Sensing [Copy link]

【Guide】Current mode control is widely used in switch mode power supplies due to its high reliability, simple loop compensation design, and simple and reliable load sharing function. The current sensing signal is an important part of the current mode switch mode power supply design. It is used to regulate the output and provide overcurrent protection. Where to place the sense resistor. There are three common current sensing methods in switch mode power supplies: using a sense resistor, using the MOSFET RDS(ON), and using the DC resistance (DCR) of the inductor. ADI technical engineers have compiled technical information on [Switch Mode Power Supply Current Detection] for everyone, hoping to be helpful to everyone. The contents are as follows: Switch Mode Power Supply Current Detection - Part 1: Basics Switch Mode Power Supply Current Detection - Part 2: Where to Place the Sense Resistor Switch Mode Power Supply Current Detection - Part 3: Current Detection Methods
