Kiran M

Part Number: TPS62903-Q1

Hi,

We are using TPS62903QRYTRQ1 buck in our design. It is given in datasheet, either 2MHz or 1MHz is the switching frequency.

How to set switching frequency for this buck?

Please help.

Thank you.

Hello Sir,

The Fsw of 1Mhz or 2.5Mhz can be chosen by setting MODE/S-CONF pin as 8.3.1 in datasheet shown:

Thanks
