Part Number: TPS2421-2 Other Parts Discussed in Thread: TPS25980 , TPS2597 Hi TI experts,
In my design, i have put TPS2421-2 as current limiter after a flyback converter. Below is the schematic.
P12V_EFUSE comes from flyback output. +12V will be provided…
Part Number: TPS2421-2 Hi Team,
My customer report that they use a Rset=49.9k, and expect ILIM=[3.6A, 4.4A], and ILIM≥3.6*1.5=5.4A. But during test, the OCP is trigged at Iout = 3.1A. And the current will rebound to about 3.1A. Is this normal?
Datasheet…
Part Number: TPS2421-2 Hi Team,
1, The Iout,max =3A, when using Rset=49.9k, the fault current threshold is [3.6, 4.4]. Is there any risk?
2, To have larger margin, customer using 40.2k to make Iset = 5A. Is it ok to connect a Rset lower than 49.9k. We…
Part Number: TPS2421-2 Dear TI experts,
My customer asked about UL certification of the parts which they use now.
I found that some parts (especially efuse) have UL certificate itself, but most of the other parts do not have UL certification.
Do you know…
Part Number: TPS2421-2 Hi Team ,
My customer used the 80.6Kohm at Rset pin wonder to let the OCP range around 2.2A ~ 2.8A.
But they will see some of device OCP run up to 3.42A and the fail rate is 8/1152.
The SCH as below , please help to check if this…
Part Number: TPS2421-2 Hello E2E,
The FLT-pin is pulled up to DC5V by 47kohm resistor. The FLT-pin has a temperature dependence, the FLT-pin voltage is to been clamped 3-V at -20degC. The FLT-pin voltage rise up to 5V at room temp. As the temp gradually…
Part Number: TPS2421-1 Tool/software: Hi All,
I have a question about the TPS2421-1.
I posted this on E2E before, but I'm posting it again since I didn't get a reply. https://e2e.ti.com/support/power-management-group/power-management/f/power-management…

Hi,
In datasheet table, VIN Bias current at /EN=0 is typ 3.9mA.
Does it means that TPS2421-2 consume the 3.9mA current during operation?
Customer needs the device which…
Part Number: TPS2421-2 Hello team,
The datasheet is saying "UL 2367 Recognized File No. E169910", so could you provide the UL recognized materials or test report to us? My customer is gathering such a safety related information.
Regards,
Ish…
