Dear Team,
We are currently in the process of designing a board that requires a power supply with a wide input voltage range. The primary power source will be an…
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 Tool/software: Hi everyone,
I'm using the TPS552872 buck-boost converter from TI in a buck configuration, and I'm observing some unexpected switching behavior. Although I’ve configured…
Part Number: TPS552872 Tool/software: In the datasheet it states that boot pins must have value of 0.1uF capacitors. Is this effective capacitance (including drift due to tolerance) or typical capacitance (tolerance not included).
Part Number: TPS552872 Hi, In the TPS552872 is the internal current sense bidirectional? I have used the IC for bidirectional current flow and it has no problem at all regulating it. Therefore I have assumed that the internal current sense is bidirectional…
Part Number: TPS552872 Tool/software: Hi,
We use the TPS552872 as a 12.6V Battery charger, with the I_limit set to 3.3A (15mOhm R_sense) 400kHz switching freq.
Our current implementation is working and we see that current is limitied to 3.3A as…
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 Other Parts Discussed in Thread: TPS552872 Dear Friend
I am using TPS552872-Q1 in one of my project and looking for technical support for specific design.
I don't use current limit and no requirement of cable voltage drop…
Part Number: TPS552872 Tool/software: Hi, I have problem following equations from TPS552872 datasheet for compensation RC network connected to the COMP pin of the IC. If i plug the numbers into the formulas for RC, CC and CP I am getting resistance in…
