Part Number: TS5A3159-EP
Other Parts Discussed in Thread: TPS54260

Dear Team,

There is good new that we DIN the TPS54260 in customer's new project.

Customer have some questions as below, could you help to support it?

1. If we don't give V+ voltage, is PIN 3 conduction? 

2. if we give power for this chip, we can control COM to NO or NC?

Many Thanks,
