Part Number: LM5143-Q1 Hi TI Expert,
For the bootstrap circuitry, we have external diode powered from VCC pin to HBx.
Since we're facing some shortage issue from original vendor so wondering whether we have any guideline on how to select a proper…
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 , LM5170 Tool/software: I am using LM5143 in IBB configuration like the diagram below. Would the controller be able to support current flow in the opposite direction? The customer is curious…
Part Number: LM5143-Q1 Tool/software: Hello,
Why is the maximum output current of the LM5143-Q1 limited to 40A even though it is an external FET DC/DC controller?
Thanks,
