bernd beisch

Part Number: TPS62872

Tool/software:

Dear Sir or Madam, We would like to use the TPS62872Z0WRXSR. The input voltage is 5V and the output voltage must be 3.3V. How do we connect the Vsel input? We do not want to use I2C.

Hello Bernd,

The TPS62872Z0WRXSR does not support a startup voltage of 3.3V without I2C configuration.

You could use the automotive versions TPS62872Y2QWRXSRQ1 or TPS62872N2QWRXSRQ1 with 47kOhm to Vin to achieve this, see Datasheet

Regards, Werner
