Part Number: TPS561208 Tool/software:
I plan on using TPS561208 for a 12V to 3.3V buck circuit. For testing purpose I need the data of line and load regulation. The load regulation is pretty straightforward. I am having issue finding out the Line regulation…

Tool/software:
We are using TPS561208DDCR to convert 12 to 3.3V as shown in the schematic below.
In our use case we have noticed that the PMIC behavior of the IC changes under potted condition of the board (The potting material…
Part Number: TPS561208 Creating a design for a customer.
Do you all see any problem with this quad isolated output flybuck based on the TPS561208? The primary side inductors are all in parallel so the effective primary side inductance is 22 uH/4 = 5.5…
Hi Rohit,
Switch node ring is a little higher with higher loading. could you share how you test and test waveform?
TPS561201 and TPS561208 switching node ringing is same.
BRs,

Hello,
We use a TPS561208 to convert 12V power supply into 5V output and further down to 3.3V ouput with LDO to power the MCU.
At the same time, we have another power source coming from USB and the requirement is to power the…
Hi,
Only TPS561208 is available in my circuit. I mean there is no other unit. I'm just trying this circuit. Maybe the TPS561208 IC is broken, so I changed it and tried it again, if you mean it. The result is always the same.
Part Number: TPS561208 Other Parts Discussed in Thread: TPS563202EVM Hi,
on the SPEC in section 10.1 it is recommended not to route the switching under the device. can help to elaborate more why it is not recommended?
in my design i've routed it beneath…
Part Number: TPS561208 Dear TI Team,
We designed PCB as per your reference circuit for part number TPS561208 DC DC. We applied input 12V but we got variable output. I have attached schematic of circuit. Please see the below attached file and help us…
Part Number: TPS561208 I have a unit that appeared to be sensitive to input ripple voltage and would catastrophically literally burn up. I have been investigating to find a root cause of why that might occur. I moved on to another unit in the design and…
Part Number: TPS561208 Other Parts Discussed in Thread: TPS54320 , Our end customer asked to relay a question. They used the TPS54320 on a previous design, and like the TPS561208, the absolute input voltage is 2-3 volts above the recommended maximum of…
