Hi,

Could you tell me about the SW-GND shortcircuit test of TPS542941.
Customer has broken TPS542941 After short test.
When SW-GND shortcircuit test ,
OCP protection of TPS542941 does not exercise it, and is TPS542941 broken?

Best Regards,
Yusuke/Japan Disty

    I do not currently have access to the original testing (which was probably done on the similar TPS54295 device). but I can tell you that sometimes the device may be damaged by shorting SW to GND. It may depend on the available input current from the VIN supply.
