Part Number:TMS320F28377S
I created a simple model of this buck converter in Matlab Simulink using the specs given in the datasheet. Using a 200kHz switching frequency and 4.8 uH inductance, I get a large current ripple due to the low inductance value. I was wondering if this was the actual value as stated of 4.8 uH or if there is a discrepancy? Also implementing current control in the model is difficult due the large ripple. When I went through the open loop/closed loop examples in TIDU986–September 2015 documentation, there are no large variations in the output: Gui_IL1. This is why I'm asking if anyone knows if 4.8 uH is the actual value of the inductor in the buck converter.
