Part Number: TPS543B20 As per datasheet, calculated the Fsw(405KHz), by selecting RT(48.7K)
But, practically SW Node Fsw is 442KHz. Why?
I attach my schematic and SW Node waveform.
Kindly give me feedback asap.
Thanks&Regards

Part Number: TPS543B20 Hi expert,
My customer has some questions on 5V input application.
If the Vin is 5V, what is the output of BP pin?
Following from question 1, is there any limitation to use 5V for input?
Thanks,
Oliver
Part Number: TPS543B20 Hi,
We are using TPS543B20 sense regulator for voltage conversion from 12V to 1.1V in non-stackable mode. We would like to know whether ENABLE pin is open drain or push-pull, in datasheet it is mentioned as ENABLE Pin has an internal…
