Tool/software:
Hi,
We use the LM5176 in the buck circuit, the input voltage is 24V, and output voltage is 12V;
Now, the temperature of the MOSFET will rise above 80℃ when the output current more than 5A;
Plesae refer to our schematic diagram and waveform and avise how to solve this issue, thanks.
1. The schematic diagram:
2. The ligh load for 12V output voltage
3. The 6A output current load:
4, The yellow line is L_gate, the red line is H_gate, the blue line is SW1 line;
5. Please kindly provide your comment for this issue, thanks.
