Power Tips: Controlling Power Supplies with Multiple Loops


Date: October 2, 2015

Usually the output voltage of a power supply is regulated and provided to a load.  A battery charger uses two loops: one to control the output voltage and another to control the output current. In this Power Tips "Ask the Expert" video, Dave asks TI’s Robert Taylor to explore how those loops interact with each other.
