My question is about LM5122 synchronous boost controller.
Q1) if I have External Vcc supply, mean that I no need Vin pin to start up or supply voltage to VCC regulator. Then in this case can I not use this Vin pin by direct connect Vin pin to Vcc pin or not.
Or This Vin pin still need to connect to input capacitor for IC functional?
Q2) My Vinput max is 60V, But in datasheet specify IC Maximum input Voltage: 65V & Absolute maximum rating is 75V. In case of any Vin transient more than 65V but not over 75V, what happen to this IC, it will damage or malfunction ??
