TPS62902: R3 Selection Mode/S-Conf pin

Part Number: TPS62902

For this part, if R3 (Mode/S-Conf) resistor is 118 K it will operate in mode 16 (VSET, 1MHz, no discharge, Forced PWM)

What if the resistor is larger than 118 K, will it remain in mode 16?

If yes, then I can use a standard 10% tolerance resistor > 131.1 K ( e.g. 150 Kohm)?

The part will still operate in mode 16 correct?

Regards,

Mike

Also for mode 12, a 49.9 K resistor is specified. What if a 50 K is used, will it still work in mode 12?

Hello,

E96 Resistor Series, 1% Accuracy is required. for 118K is a standard value abd only 1% varaition is allowed. the same applies for all values in table 7-1 and 7-2 tables in the datasheet.

thanks
