Part Number: LM7480 Tool/software: Hi team,
Our customer is considering a circuit using an input capacitor with the LM7480.
When the load is shorted, the discharge from the input capacitor will momentarily exceed the SOA of Q2, damaging the Q2 FET.

Hi Shiven,
Thanks, for this Information. I think I will use the LM7480-Q1 .
What is the better Mosfet in Back-to-Back configuration. I have a voltage of 24V and a max. current of 5A. What Mosfet is better in this configuration? the AON6240 with lower RDSon…

Part Number: LM7480-Q1 Other Parts Discussed in Thread: TPS73801 Hello TI,
I was looking at this thread LM7480-Q1: Reason for bidirectional vs unidirectional TVS diode on the input side - Power management forum - Power management - TI E2E support forum…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: LM7480 , Tool/software: Can a LM7480-Q1 be used on a 3.3V output circuit, as the VS > 3V for operation? As the 3.3V output would fall in a current limit situation, would supplying the VS pin form…
Hi Gareth,
Positive TVS needs to be >200V. Here D3+D4 combined is rated for 200V.
You can also choose a single 200V TVS+ and SMBJ33A for TVS-

Part Number: LM7480-Q1 Other Parts Discussed in Thread: LM74800-Q1 Tool/software: Hi, please review the schematic below in particular for reverse polarity protection up to 45V. Some parts of the actual schematic (bypass capacitors and input/output filters…
Part Number: LM7480-Q1 Other Parts Discussed in Thread: LM74800-Q1 Tool/software: Hi Team,
In schematic below, LM7480-Q1 is used to drive Q1. And the Vout2 will be a fewer lower than VBAT.
So customer wonder if Vout2 can be used to drive Vs pin of LM7480…
