Part Number: TPS57040-Q1 Tool/software: Hello, I would like to send a new IMDS SX000019713 (TPS57040QDGQRQ1, IC) that does not contain the 8.1 classification
Please send to NVision 126016.
Thank you and have a nice day.
Part Number: TPS57040-Q1 Other Parts Discussed in Thread: TPS54040 Hi Expert,
My customer is facing shortage for TPS57040-Q1, and find that should be P2P compatible between TPS57040-Q1 and TPS54040. Currently, we are making detailed comparison between…
Part Number: TPS57040-Q1 Hi,
I have soldered TPS57040 10MSOP on PCB 10 times, and still not working.
The chip i have here is package marked "5704Q".....is this correct for the TPS67040Q?

Hi Doug,
On page 22 of the TPS57040-Q1 datasheet figure 41 and equations 12, you can see the maximum frequency is limited by VIN.
I checked in WEBENCH, as I decrease the input voltage and the maximum frequency increases.
Can you check with equation…
Part Number: TPS57040-Q1 HI Team,
I'd like to ask you about the output voltage issue of TPS57040-Q1. My customer is testing their board that TPS57040-Q1 is applied, but there is the output voltage drop issue like an attached file. They are testing the…
Part Number: TPS57040-Q1 Other Parts Discussed in Thread: LMR33610 Dear team,
My customer plans to design a discrete battery charger solution for 12V battery with our TPS57040-Q1 device.
He hopes to use external error amplifier instead of the internal…
Part Number: TPS57040-Q1 Hi Team,
my customer needs to know if the hysteresis value spread across a production batch or is it stable? The second question is if one reel just consists of parts from one batch or is it possible to have more than 1 batch…
Part Number: TPS57040-Q1 Hi Team,
I'd like to ask you about the measurement data of 5V start/stop voltage. there is no detailed measurement data on under 5mA output current in datasheet like the graph below. Please share it with me if you have the data…
Part Number: TPS57040-Q1 Dears,
I'd like to ask some issues on UVLO adjust resistors and Vstop/Vstart voltage of TPS57040-Q1. I think that there is a hysteresis issue under condition of Vin=5.13V, Vout=5V, R1=453kohm, R2=100kohm like an attached file…
Part Number: TPS57040-Q1 Other Parts Discussed in Thread: LMR33610 , LMR36506 Hi,
Customers have some Iq issue that its Iq is bigger than the value on the datasheet.(155uA @ 12V)
Could you recommend other devices that have lower Iq?
They said pin…
