Part Number: TPS544B20 Other Parts Discussed in Thread: TPS544C20 , Hi,
We are seeing very inaccurate output current readings from the device across multiple samples. We have two similar designs, one based on TPS544C20, and another based on TPS544B20. Both…
Part Number: TPS548B22 Other Parts Discussed in Thread: TPS548A20 , , TPS544B20 Hi team,
Customer is doing a 5V input switch project, and they want to check with us if TPS548A20 TPS548B22 TPS544B20 could support 5V input and 3.3V output application, datasheet…
Part Number: TPS544B20 Other Parts Discussed in Thread: TPS544C20 Hello,
This question is intended for both TPS544B20 and TPS544C20.
Is it OK to write NVM while the device is in operation and the output is enabled? Does it have a negative impact on a…
Part Number: TPS544B20 Other Parts Discussed in Thread: TPS549B22 , TPS546B24A HI TI expert,
We need a power device to meet the following requirements: 1. Typical VIN=12V
2. default VOUT=0.82V without programming
3.Vout can be adjusted on the flying
4…
Part Number: TPS544B20 My Customer is using TPS544B20RVFR in our design .In datasheet , they didn’t get the clarity on the logic levels of the SMBUS signals.
Please provide the info regrading Vih, Vil, Voh, Vol for data , clk ,alert signals and…
Part Number: TPS544B20 Other Parts Discussed in Thread: TPS544C20 We have three designs on our current board based on your TPS544B20/TPS544C20 IC. Two of them are very similar, a 1.0V and 0.8V design. The feedback network is almost identical, the have…
Part Number: TPS544B20 Hi,
I would like to know whether CNTL pin of TPS544B20 can be left floating so that TPS544B20 can be enabled by default without any programming.
Thanks,

The trace-length of the sense lines is not critical, though transmission line delay through the power-path could be. Parasitic trace inductance and heavy bypass capacitance at the processing can add delay between the energy delivery at the…
Part Number: TPS544B20 Other Parts Discussed in Thread: TPS544C20 Hi,
We are planning to use TPS544B20 regulator for core supply in our system. The core supply will be enabled after the IO supplies are turned ON as per sequencing requirements. I need to…
Part Number: TPS544B20 Hi,
Customer found TPS544B20 would have a overshoot during start up condition with default setting.
Here is the schematic. could you give some suggestion how to avoid the issue?
Thanks.
