Part Number: TPS54540 Dear support,
in the last months we're facing a problem over a DC/DC stage based on TPS54540 regulator, it's mounted on a product landed the production some years ago but in the last batches we got a failure rate around 5%: the…
Part Number: TPS54540 Hi
The board is back and currently undergoing debugging. The circuit is related to the M.2 5G module.
The current issue is that AI analysis suspects power instability is causing 5G connectivity anomalies, which results in an…
Part Number: TPS54540 Hi TI
We use TPS54540 in an inverting buck configuartion. We have automated test systems that analyse the switching waveform of the DCDC converters, for verifying proper function. But on one out of 50 units, our inverting buck…
Part Number: TPS54540 Tool/software: Hi, For the IC TPS54540DDAR can we supply more than 8.4V to the ENABLE PIN to set " Under Voltage Lockout"? if so what is the maximum voltage we can supply.
in datasheet it is mentioned that when we exceed more than…
