Part Number: TPS2553-1 Hi Team, I have a question about current limit feature of TPS2553-1 and would like to send my customer's schematic and waveform in offline. Could you send e-mail to the following? yaita-k@clv.macnica.co.jp Your support would be appreciated…
Hi, Kanemaru-san,
There's no problem with 4ms toggle time. I did a test to validate it.
For EN toggle time, even a 1us Low level toggle time will enable TPS2553-1 from latch off.
For Vin cycle time, even a 100us low level cycle time will power on…
Part Number: TPS2553-1 Hi, team.
My customers are planning to use TPS2553DBVR-1.
My customer is trying to check the Current Limit Function, please check with the confirmation method below and tell me whether there is no problem.

Circuit diagram is very typical.
3.5V Vin, 1uF input capacitance, 100nF on the output, Fault pulled up to Vout by 100k, EN pin via 100k to the Vin.
The situation is following.
Current treshold…
Part Number: TPS2553 we listed in datasheet that TPS2553 is UL Listed -File No.E169910 and NEMKO IEC60950-1-am1 ed 2.0.
please help to share the file for us.
Part Number: TPS2553 Hi there,
where I can download the IEC60950-1-am2.0 Report for TPS2553? I have tried to find it on both TI's website and NEMKO's website but couldn't find it. thank you
Regards,
Kevin
Is the external power supply removed from the board when you plug xds110 usb cable to the board? The board can be powered by either from usb cable or from J17.
If only USB cable is plugged, what is the voltage level of at point 1 in below screenshot: …
Part Number: TPS2553-1 Hi Team, My customer is evaluating TPS2553-1 in his system. He set electrical load and increased load current gradually (15mA step), he found the state that shows output current is limited to the current limit value he set however FAULT…
Part Number: TPS2553-1 Is it OK to have the EN voltage up before the IN voltage comes up? Any extra current leakage or other concerns?
The datasheet abs max seems to imply there will be no issue as long as it's between -0.3V and +7V..
Thanks,
Dan …
Part Number: TPS2553 Other Parts Discussed in Thread: TPS2065C , TPS25221 , TPS2051C We are using a TPS2553 to limit current output from a DC/DC converter with 5 V output (not a USB application, though). The circuit is as shown below, set for a nominal…
