Part Number: TPS548D22 Hi Team,
Our customer is using TPS548D22 and he is asking what is maximum output current of this device since datasheet shows OCP vallley current can be set at >70A with 240kohm in Figure 15. Can you clarify what is maximum current…
Part Number: TPS548D22 Hi Dear All Now, I'm designing circuit use TPS548D22. TPS548D22 is setting output voltage= 0.71V, f=650kHz, input voltage=12V. I am looking for better transient response. From the measurement results, RCSP_FSEL[1:0]=01(Rx1) was better…
Part Number: TPS548D22 HI,Dear all
Could you please tell me about RCSP_FSEL[1:0] in the settings determined by FSEL register? What are you configuring on TPS548D22 ? It seems that the [internal ramp amplitude] is set, but please tell me how to determine…
Part Number: TPS548D22 Hi team,
My customer is designing a system power supply based on TPS548D22, and have below requirement, please help to give your professional advice.
Vin=12V, Vout=5V, Iout_max=30A, Iout_ripple<200mV. Now there are two inductor…
Part Number: TPS548D22 Hi Sir,
We still can't fix customer's issue at TPS548D22 design (can't adjust output voltage to any voltage except 0.6V). Customer will redesign their board but need to know the question at their design. Would you please help to…
Part Number: TPS548D22 Hi expert,
Do you have TPS548D22 short circuit test waveform can share as a reference?
What customer measured seems like OCP behavior. We expect Vo shall drop to 0 right away. Although they used E-load but they use multiple and…
It looks like there is some very severe spikes on VOUT corresponding to the switch node transition.
I don't see the switching node, but I would recommend looking at the grounding of the TPS548D22 and the output capacitors.
You could try increasing…
Part Number: TPS546D24A Other Parts Discussed in Thread: TPS548D22 Hi,
I want to check TPS546D24A's OVP mechanism. In TPS548D22, it turns on low-side FET until NOCP is triggered, then high-side FET is turned on for minimum on time. I think it has problem…
