TPS254900-Q1: TPS254900-q1

Part Number: TPS254900-Q1

Dear Sir,

We tested TPS254900-Q1 EVM, it was found that even when CTL1 and CTL2 are kept low (operated in client mode), there’s 2.x V on OUT pin.

The following setups.

1. 12V applied to J1.
2. Short J2; open J3.
3. Short pin 3 with pin 4 on J6; short pin 5 and pin 6 on J6.
4. Around 1.5V was measured on J5’s VBUS pin. (No load is connected on J5)

 Could you help us learn what might be wrong?

Thanks, Ian.
