Inductor Selection for SMPS Circuit of STM32H563MIY3Q
For the SMPS mode of the STM32H563MIY3Q, the datasheet recommends an inductor with an RMS current (Irms) rating of 1.4 A. However, the actual core current is only 50 mA. Is it acceptable to select an inductor with a lower Irms rating, such as 500 mA?
