Part Number: TPS2373

Hi,

Please see the picture below:

1. the Duty and the resistor are different between TPS2373 datasheet and EVM, which one I should follow?

2. Is this typo? Or any reason?

Thanks,

C.T.

Hi CT,

1. We recommend using 60.4kohms to attain 8.1% duty cycle, while 53.6k will result in 7% duty cycle. Shorting will result in 12.5% duty cycle.

2. These are typos that need to be corrected.

Thanks,
