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?

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 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 interna…
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…
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 I'm using the TPS57040 in an automotive application. One of the reasons I selected this part is the adjustable switching frequency. I intend to switch around 2Mhz.
I tried to use Webench to come up with some numbers to compare…
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 to pin…
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 Hi,
I am working on worst case analysis for the TPS57040-Q1 circuit. The datasheet of the device indicates that the minimum controllable On time is typically 130 ns. Then, what is the worst case value for the minimum controllable…
