TPSM82912: Output Voltage

Yuta Nishie

Part Number: TPSM82912

Tool/software:

Hi,

I connected a 100Ω or 68Ω load resistor between TP4 and AGND and checked the output voltage. However, the output voltage was 0V.

Could you please check whether there are any problems with the circuit diagram and layout?

Best Regards,

Nishie

Hi Nishie,

The schematic is fine. What happens if you don't connect any load? Do you observe 5V at TP4?

Hi Gautam-san,

Thank you for checking the circuit diagram. Is it correct to understand that there are no problems with the layout?

I also checked the output voltage with the load removed, and it was 0V.

Best Regards,

Nishie

Nishie-san, by any chance the chip is damaged? Did you try replacing the same with a new one?
