Part Number: TPS40422 Tool/software: Hi Expert,
May I have your help to check this case ?
Does TI have a version or could reprogram the TPS40422 Dual-Output or Two-Phase Synchronous Buck Controller with PMBus Interface where VOUT_MODE pmbus command…
Part Number: TPS40422 Hi there,
Could you please confirm the read voltage accuracy of TPS40422 device?. What is the 1LSB resolution for Read_VOUT?. From data sheet I could not get this information.
Thanks

Part Number: TPS40422 Tool/software: Hi expert,
Customer used TPS40422 for 12Vin to 0.88Vo/40A and use the calculation tool for compensation but find the phase/gain margin is not good.
Would you please advise how to adjust the stability?

Hi expert,
Customer used TPS40422 and setup a test procedure to disable and enable the device by controlling CTRL1 pin only instead of removing the VDD. However they see one board got a problem that after disable the TPS40422…
Part Number: TPS40422 Hi TI experts,
When keep monitoring the TPS40422 output voltage (1 minute interval) through PMbus, observed high voltage spike randomly.
example for 2.5V output:
2023/07/30 19:50:29 A-TPS1-1 crossed threshold (range: 2375mV…
