Part Number: TPS2546
Other Parts Discussed in Thread: TPS2549,

Hi team,

can the TPS2549 replace the TPS2546 directly in below application? only Pin 4 CS function is difference, can we replace TPS2546 without any hardware change?

thank you

Hello,

You would need to implement the feedback resistor network for the CS pin. The rest of the functionality should be identical if you keep the TPS2549in CDP mode
