Part Number: TPS720
I am interested in learning more about TPS720xx in the DSBGA package. What is the reliability comparison for underfill or not underfill?
Hi SHH,
The current limit loop has a response time where this inrush peak happens and CL kicks in, by the time CL has responded the IOUT is already below the current limit, so the waveform looks as you've shown. This behavior is not unexpected for larger…
Part Number: LP5910 Other Parts Discussed in Thread: TPS720 , We currently use a TPS72010 and a TPS72012 to generate 1.0V and 1.2V outputs from a 1.5V supply. The BIAS-pin of the TPS720 is connected to 3.3V. While this generally works well and saves a lot…
Dear Kai,
Many thanks for your help.
Here is the demand:
Vin: 1.4v
Vout: 1.3v
Current: 50mA
Any suggestion for this case?
I check this via TI website, are TPS720 and LP5952 suitable for this case?
Many thansk.
Hi Mark,
Could you let us know what the current output requirement is? Without knowing this value, I can think of TPS720 which has a rating for 1.09V (typical) to 1.40V (max) for Bias drop voltage. This device should work better for your application.…
Hi Jeffery,
The abs max rating is correct correct. There is a diode (Vf = 750mV typ @ 25C) from Vbatt to Vin. Take a look at the TPS720 - it is a similar device with a similiar footprint.

Hi David,
Anytime that Vout exceeds Vin there is the potential for reverse current. While TPS720 has a body diode that will conduct this current from Vout to Vin, the current will not be limited. If extended reverse voltage operation is expected, an external…
Hi Avatar,
Please take a look at the TLV733P, TPS720, and TPS727 families. Each of these families include a 1.5V fixed output option in a small package size you list.
Very Respectfully,
