Part Number: TPS62120 Hi experts!
In section 7.5, I am confused by the specs for Vfb:
Could you please explain what these specs mean? For example, when the output voltage falls below a threshold and the comparator determines the switch must…
Part Number: TPS62120 Other Parts Discussed in Thread: TPS62122 Hello experts,
Do you have EOL plan of TPS62120/TPS62122?
My customer wants to know EOL information.
Thanks and best regards,

Part Number: TPS62120 Good day Colleagues,
Could you tell me, how to calculate Cff value for low impedance feedback divider? Datasheet examples used for calculations very high resistors (about 500kOhm).
While my customer is using 10k and 2k resistors…
Akshay,
There are some different scenarios. If the TPS62120 is powered and enabled it will try to regulate to its set 2.8 V operating point. There is no provision for current sharing so one supply may provide all or most of the load current while…
Part Number: TPS62120 Hello,
I have a question for Ta and Tj range for TPS62120.
I think usually Tj is used for operating temperature range of power devices. But TPS62120 datasheet defines its temperature range by both Tj(-40 to 125C) and Ta(-40 to…
Part Number: TPS62120 Hey,
We are currently using the TPS62120 for getting our Vin of 12V to 3.3V voltage.
The application consists of a microcontroller which reads out some sensors. The controller is put to sleep for some time, wakes up, reads the…
Hi Emil,
I think it's OK to use a high-Q inductor here.
1K prices are the same with two devices. From thermal perspective, TPS62120 would be better, as the RthetaJA is smaller due to its thermal pad. For EMI performace, it should be similar as long…
Part Number: TPS62120 Other Parts Discussed in Thread: TPS62745 , TPS62840 , TPS62175 Hi team,
My customer need one buck device, which is used to convert 7.2V supply to 3.6V and its output capability should be greater than 50mA. Now TPS62120 is recommended…
Hi Jeff,
This app note, found on the product page, explains many details on 100% mode: www.ti.com/.../slyt747.pdf
In the TPS62120, the PMOS is simply drawn backwards.
Dear Sir,
I would like to check whether is it possible for me to perform this application as the Vin:7v@5mA and Vout:3.3V@20mA. I had run a simulation and it says that this part is able to meet. Please help to advise.
