TPS560430: replacing TPS560430YDBVT with LMR50410XDBVR

Part Number: TPS560430

Have sourcing issue with TPS560430YDBVT and thus plan to drop in LMR50410XDBVR. FYI, I am using TPS560430YDBVT to generate 1.2 and 3.3V from 5V input. From the datasheet, the new part is pin compatible. Not sure if I missed out other parameters.

    Hi Ioi,

    The main difference is the switching frequency. TPS560430YDBVT is with 2.1MHz while LMR50410XDBVR is 700kHz, which might influence your inductance/capacitance design. You can use Webench to simulate that.
