Part Number: TPS552872-Q1 Dear TI Support Team,
We are planning to use the TPS552872-Q1 buck-boost converter in our design. The system input voltage can be either 12 V DC or 24 V DC, and the required output voltage is a regulated 12 V DC. Based on…
Part Number: TPS552872-Q1 Dear Team,
I would like to use TPS552872-Q1 and connect EN and EXTVCC together.
The EN voltage will be maximum 3.3V
This way the converter should be enabled and select Internal Regulator at the same time. Unfortunately…
Part Number: TPS552872-Q1 Dear TI experts,
My customer made their schematic using TPS552872QWRYQRQ1. Could you review this schematic?
Best regards,
Chase
Part Number: TPS552872-Q1 Hi,
I'm trying to use the TPS552872-Q1 to charge a supercapacitor bank.
The input is 24v regulated, once the supercaps are charged output current is <1A.
After misreading the datasheet I had originally pulled EN up to VCC…
Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS552872 Hi Please check my TPS552872 schematic, as I am having issues with chip heating and really loud switching.
Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS552872EVM Hi, this is my current sensing circuit. The output voltage is 12.2V.
Rsns=47mohm nominal value Iout_limit=1.06A
With a 34ohm load, the current is limited to 1.95A, Vsns=90…
Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS552892 Tool/software: Dear TI experts,
My customer wants to use TPS552872-Q1 for their new project.
I want to check the design requirements but TPS552872-Q1 does not support WEBENCH simulation…
Part Number: TPS552872-Q1 Hi TI expert,
We notice the TPS552872-Q1 DS didn't mention about the Load/Line regulation.
We can find related waveform but we will need such data in the EC table for reference.
=> Figure 8-10/8-11
May I know whether…
Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS55289 , TPS55289-Q1 , TPS552872 Dear TI experts,
Do you have any EMI and EMC test results of TPS552872-Q1?
The results on the EVM is also fine.
My customer will check the results and…
Part Number: TPS552872-Q1
Hello,
I have been referencing the datasheet and EVM User's Guide and would like to request a schematic review of my circuit, which uses the TPS552872QWRYQRQ1. Just the connections for U3.
Generally requirements:
1…
