Part Number: TPS548D22 Hi - I'm looking at TPS548D22 - Is there any way of margining the output voltage of the device using an external D/A converter or PWM.
(please see Slaae23 - Voltage Margining and Scaling Circuit With Current Output Smart DAC…
Part Number: TPS548D22 Tool/software: Hi.
Im designing 30A 0,85V buck converter with TPS548D22RVFR. I want to ask about switch-coil PCB trace. PCB is 1oz copper, and connection between coil and switch is about 200mil wide - should, or can i use second layer…
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…
Hello NIK,
From an UVP prospective, the device is working as expected. It will not shut down if it is not below the 68% threshold.
now, why VOUT does not drop below that, i am not sure.
Can you measure the inductor current?
The device is valley current…
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…
