TPS43060: drive EN pin on TPS43060 through digital output of a microcontroller (0 to 3.3V)

Nitish Agrawal

Part Number: TPS43060

Hello,

Can EN pin on TPS43060 be driven through the digital output of a microcontroller (0 to 3.3V)?
In such a case, should there also be a pull-down resistor (say, ~1Mohm) to ground?

Regards,

Hi Nitish,

Yes the EN pin can be driven by a micro. I would recommend you to add 10k to 100k pull down in case the the micro link is broken and the circuit gets startup by itself.

Thanks,
Youhao
