about TPS54362 EN pin connection

Jerel Xu

According to TPS54362 datasheet,EN pin should be pulled up or down,not be floated.However,from Figure 17,EN pin is pulled up to V_REG(output voltage),during start up,V_REG should be 0,how to guarantee that TPS54362 can start up normally?Thanks!

Hi Jerel,

That is typo mistake in the TPS54362 datasheet on Fig17, instead of Vreg it should be VIN.”

Thanks

There are couple of typos in the datasheet. The EN input should be pulled up to VIN on the application diagram on page 21. There is an error in the PIN FUNCTIONS table on page 6. The EN input has a 500 kohm pull-down resistor in series with a 6V clamp, so leakage current will only be present when EN > 6V.
