Part Number: TPS548D22 When using the TPS548D22 without an external feedback resistor network (using VSEL to set ouput voltage) and without using the remote sense input (RSP connected to output and RSN connected to load return), how should a loop stability…
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 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 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…
Part Number: TPS548D22 Tool/software: Hi Sir,
I have a Design Spec
Vin =5V, Vout=1.1V, Iout=30A, the FSEL PR231 is setting 90k9
the switch frequecy is unstable at havey load, it look like sub-hamonic Osclliate ?
I adjust the resistance PR231…

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…
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…
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…
