Part Number: TPS62840 Hello Team,
I see a disconnect in the specifications of quiescent current in the data sheet:
According above table Iq for VIN+VOS results in 92nA.
Looking at below graphs adding VIN+VOS at 25°C results in about 75nA.
The 75nA…
Part Number: TPS62840 Hello Team,
may I kindly ask you for the difference between A and B, please?
In both cases the device is not switching, correct?
Thanks for clarification,

Part Number: TPS62840 We are using the TPS62840DLC on a design and because it meets the requirements and the space constraints. There may be are reason we want to up the output voltage slightly above 3.3V.
Is there undocumented resistors that would allow…
Part Number: TPS62840 Hi, I like to use the TPS62840 as a replacement for another buck that I used,
I would like to know if there is any documentation for testing emissions on this device.
thanks
Hi Excel, Sorry for this waiting time. I found the solution of my problem, and I used the efficiency data to calculate the input current. Regards, Ghilain
Part Number: TPS62840 Dear Team,
Initially we used TPS62840DLCR in our design to generate 1.8V from 3.3V but now it has been out of stock and reporting long lead time.
I checked that TPS62842DGR is having same parameters and characteristics like TPS62840DLCR…
Part Number: TPS62840 Hi team,
Do you have any data of minimum value of Vth_UVLO+ (1.72V typ)? and is it definite that Vth_UVLO+ > Vth_UVLO- ?
Best regards,
Hideki
Hi Xiaoli,
I think there is a system load that is pulling current from the TPS62840. Without a full schematic and layout, it is not possible to find the root cause. And you also confirm that on the EVM, the input current is very small. So, it is definitely…
