Part Number: TPS54424 Hi
I'm confused about this, we use the TPS54424 to output 1.8V and it has been working fine.
A sample board lost the CAP of the BOOT pin, We found that the SW pin was shorted to GND.
When we replaced a new TPS54424 chip on it…

Part Number: TPS54424 Hi team,
My customer is using the TPS54424 now. We want to check whether the EN negative -0.42v with 2ns has risks. The waveform is below. Could you please share the comments about the risks and share the reason? Thanks.
Part Number: TPS54424 Hello team, My customer would like to use 0.1uF(0603mm size) because the customer cannot buy larger size chip capacitor. So the customer would like to use 2 pcs capacitors in parallel for CBOOT to consider DC performance of capasitor…
Anthony-san,
My customer has been asked additional questions about the TPS54424 as follows.
How is the measurement condition of the Vfb (Regulated FB voltage)? Is it at Iout = 0A? Please let’s know the Iout value.
How much the Load Regulation…
