LM5170: Operate at above 160V

Hi Chris,

Please refer to  LM5171-Q1: 200V BUS use-case .

Hi 

I can't open this page

Hi Chris,

This is possible but you may need to take care of below items:

• Use external gate drivers
• Use external current sense amps
• HV1,HV2 can support 85V max
• Peak current limit accuracy will be affected.

Hi Feng Ji ,

• Use external gate driversMy design concept remove the SR MOSFET, so there is no need to use external gate drivers, right?
• Use external current sense ampsMy design concept is to move the position of the current sensor from the high side to the low side, so there is no need to use an external current sensing amplifier, right?
• HV1,HV2 can support 85V max
• Peak current limit accuracy will be affected.
• Why?

This is my design concept, please help me check it, thank you.

Hi Chris,

Maybe UCC28070 is a better fit?
