Part Number: TPS40190 Image from a board with a busted chip.
24V was applied to the system, and there were some fireworks. This chip has a hole, and the "0190" marking code seems to align with the TPS40190. The device ABS MAX is also only around 16V…
Part Number: TPS40190 Hi, Good day. I hope everything is fine. Our customer is looking for the ESD information for the TPS40190DRCT such as HBM/CDM. I hope you could helps us provide this information. Thank you and stay safe. Regards, Cedrick
Part Number: TPS40190 Hi Team,
Do we have more accurate FB pin buck controller?
I saw TPS40190 FB pin tolerance is +/- 1%. Do we have +/- 0.5% or lower device?
Vin = 19V Vout = 0.8V Iout=19A
BR,
Roy
Other Parts Discussed in Thread: TPS40190 Hi,
I'm currently evaluating the TPS40190. The sample schematics (slur004.pdf) contain a diode D1. On the TPS40190EVM-001 it is not populated.
When should this Diode be used? I could not find any information…
Other Parts Discussed in Thread: TPS40190 Design using TPS40190, TI power controller. In our configuration we have connected up the enable pins of all 4 controllers on our card to a common backplane signal. Our equivalent pull-up value per card is about…
JW Wu,
The Soft-Start on the TPS40190 controller is established by an internal DAC using a digital counter from the switching frequency. While devices from the same lot operating at the same input voltage and temperature will generally show a tighter…
Part Number: TPS51218 Other Parts Discussed in Thread: TPS40190 , , TPS51225 , TPS51220A , TPS53015 , TPS53119 , TPS40195 , TPS40075 Customer used TPS51218 before, now they want to use a buck for Vin=12V, Vout=5V, Imax=20A, but TPS51218 can only support…
When the same control signal is used to enable two TPS4019x, it is not suggested to tie the ENABLE pins of the two TPS4019x together. The reason is as follows. Due to the process variation, the threshold on ENABLE pin which is 1.9V typical (3xV BE ) is…
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?
TPS40KType…
