Other Parts Discussed in Thread: LM5176
hi Team:
I use the LM5176EVM-HP Schematic diagram,and designed a buck-boost Power:
Vin:8-40V;
Vout=12V6A;
1. when R7 use 10mR,it can normal work;
2. when R7 use 9mR,it can normal work;
3. when R7 use 8mR, VIN from 8-13V,it can only Load with 2A;
4. when R7 use 7mR,it can normal work;
5. when R7 use 4mR,it can normal work;
my question is :why R7 use 8mR,VIN from 8-13V,it can only Load with 2A;?
