Part Number: TPS40400 Other Parts Discussed in Thread: TMS320DM8168 Tool/software: Linux Hello,
Background: On our board we use TPS40400 buck controller as 1.1V source for the TMS320DM8168. The TMS320DM8168 processor controls TPS40400 via I2C bus (PMBus…
Part Number: TPS40400 Hello,
I am trying to troubleshoot a design where HDRV is not driving the high side FET. This is a 12V to 3.3V @ 5A rail.
We are hypothesizing that the bootstrap circuitry is failing and that HDRV is not being supplied with adequate…
Part Number: TPS40400 Hi
I had one question about the output current report problem (not accurate) with the TPS40400.
The test board is TPS40400EVM-351, therefore the current sense element is the inductor’s DCR.
Please refer the inductor spec as…
Part Number: TPS40400 Hi Ti member,
I have one question about the output current report problem (not accurate) with the TPS40400.
MY evaluated board is TPS40400EVM-351, therefore the current sense element is the inductor's DCR.
The inductor value…
Part Number: TPS40400 Dear TI Members.
TPS40400 maximum output current default is 10A on datasheet.
BUT our customer said that TI member guaranteed that if disable PMBUS, the default is 12A.
Could you have some data let us refer the information is correct…
Part Number: TPS40400 Hi TI,
we have been looking into TPS40400 to supply 1.00V core voltage for a CPU. We think the current can be up to 10A, therefore we will use the voltage sense function that this part have.This CPU will handle the I2C and PMBus…
Part Number: TPS40400 Dear all,
My customer want to know reason of phenomenon below,
Osc.Freq. was changed at Iout 0 to 40A load step.
Ta= 0deg.C and C8= 4700pF no change always 400kHz Ta= -40deg.C and C8= 3300pF no change always 400kHz Ta= -40deg.C and…
