Part Number: TPS62740 Hi,
Apologies if I am in the wrong place - I could find anywhere for commercial advice.
We use many TI parts, currently in low thousands which are now on very long lead times.
I am planning batch builds with our CEM for 2022.

Part Number: TPS62740 Hi,
I will use the VOUT to supply the digital section of my board and the LOAD output of TPS62740 to supply my analog section. Do I have to include an LC filter in LOAD output as well?
Part Number: TPS62740 Hi,
I am using the TPS62740 into my design. My appplication will consume just a few mA (5-10mA). Due to pcb area constraint I need to ommit the three vias recomended on the datasheet (pg 31). Is it ok?
Hi,
First I should mention that a output voltage ripple of 9mV p2p is not a surprising result for the TPS62740. Most buck converters achieve that amount of ripple - check out the Figures 31. - 34. in the datasheet .
Regarding the measurement I have the…
Part Number: TPS62740 I am working on the dc-dc device which has good Iq (360nA).
my dc-dc has no load then we can say as I(in)=I(q)
and if the dc-dc has load then I(in)=I(q)+I(out) or I(in)=I(out) ?
which one is correct one.
please let me know
Thanks…
Part Number: TPS62740 Hi TI,
We are designing a prototype using the TPS62740DSSR as swtiching regulator. Now we are in the 4th revision of our PCB and we have realized that this component is out of stock and is expected to re-stocking in 2022.. Every converter…
Part Number: TPS62742 Other Parts Discussed in Thread: TPS62740 , Hello The datasheet suggests (to me) that TPS62742 can be used as a drop in replacement for TPS62740. If I do this can we safely say there will be no change in EMC signature, switching frequency…
Part Number: TPS62740 hey TI team,
we are using TSP62740 IC in our device. we are getting saw tooth waveform at the output of the IC (Green waveform).
we tried to reduce it by using passive LC filter(2.2uH,10uF).
can you people help us out how can we…
Part Number: TPS62740 Dear team,
Customer use TPS62740. When pass ESD test, there is some probability that no output.
Customer tried to add resistor between Vin and EN and still no output. Only they power down VIN and enable that the output become normal…
