TPS74201: startup sequence

K.Shidara
Expert 3225 points
Part Number: TPS74201

Hi Team,

Would you advise my customer's inquiry below?

---

-I use TPS74201 to make 1.5V to 1.2V, but I am creating a circuit

where EN of TPS74201 turns ON earlier than VIN due to the influence of voltage sequence.

Is there a problem with TPS74201 turning on EN earlier than VIN?

If possible, I would like to obtain a schematic of the EN part of TPS74201.

Thanks

Best regards,

Shidara

    Hi Shidara,

    Upon checking the datasheet, there is no special sequencing required with Enable and Vin. It's okay to turn on EN earlier than VIN. For the function diagram of the device, you may refer to section 7.2 in the datasheet; unfortunately, we are unable to provide a schematic of the design.
