Part Number: TPS548B28 Other Parts Discussed in Thread: TPS548A28 , TPS51220A Hi sir,
Do we have TPS548A28 & TPS548B28 efficiency curve below 10mA?
Using condition is Vin:12V / Fs:600K HZ / Vout:3.3V
Like TPS51220A below:
Thanks a lot!
Part Number: TPS548B28 Hi Team,
As shown in the following oscilloscope capture, during the load step-up, the output voltage experiences an initial undershoot followed by 3 to 4 cycles of underdamped ringing. Similarly, during the load step-down (on…
Part Number: TPS548B28 Hi Team,
When Iout=10A and Vout=0.8V, the output voltage of TPS548B28RWWR will drop first and then recover.
However, when the current was changed to 10.9A, the waveform displayed was as follows.
Why does such a difference…

TPS548A28 has a glitch issue on Power Good when power-on. What is the cause of this issue? Thanks.
Part Number: TPS548B28 Other Parts Discussed in Thread: TPS54KC23 Hi sir
I design the power by WEBENCH ® Designer. But I measure the load current is like Hiccup Overcurrent . And then it shutdown(switching stop). I have questions as below:
Are there…

Dear Sir,
refer to circuit, I need to be able to handle 0~20A loads and compensate for voltage drop.
How to design remote sensing feedback circuit.
Part Number: TPS548B28 Tool/software: Hi Team,
We are using TPS548B28 Buck converter IC.
We have observed glitch in FB voltage and output voltage. Please check the waveforms below.
1. C1(Yellow waveform) is for Enable signal and C2(Green waveform…
Part Number: TPS548B28 Tool/software: Hello Team,
When I am trying to run Pspice Transient Model for TPS548B28 IC, the default circuit(without changing any parameters) is working properly and giving correct results.
But, after making some changes…
