Part Number: TPS54424 Hello TI Team,
We are planning to use TI PN: TPS54424 in our new redesign project. Thus, I would like to check with TI whether this part is OK to be conformal coated? Reason being, our PCB will need to be conformal coated after…
Part Number: TPS54424 Other Parts Discussed in Thread: TPS54678 , TPS54318 , , TPS54335A
All newer devices with variable switching frequency (TPS54335A, TPS54318, TPS54678) I have worked with so far have formulas in the datasheet to calculate efficiency…
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 Other Parts Discussed in Thread: TPS54824 , When I compare efficiency for TPS54424 vs, TPS54824 it seems a big difference, yet Mosfet rds are the same. Why? - Patrick
Part Number: TPS54424 Other Parts Discussed in Thread: TPS568215 ,
TPS54424RNV,TPS568215RNNR switching regulators are designed as shown in the picture above. The enable pin of the ic's are driven from open drain enable output of a sequencer. I would like…
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…
