LM7480-Q1: LM7480-Q1: Priority mux and inrush current

Part Number: LM7480-Q1

Tool/software:

Hello all,

in the answer to “LM7480-Q1: Priority mux and inrush current” is mentioned:

“We do have a work around circuit to have inrush current limiting during startup while also having fast turn ON of secondary HGATE while transitioning from primary to secondary. Let me check if we can share this circuit with you.”

 

Would it be possible to share the design idea with me so that both functions can be achieved?

- Inrush current limitation in case the AUX supply is the only supply

- And fast transition from primary to secondary in case we lose the primary source during normal operation.

 

Br,

Bernhard
