Tool/software:
Hi team,
May I know wht there are two pull up resistors R1 and R17 on PGOOD pins? I think only one pull up resistor on PGOOD pin is enough.
My customer plans to remove the resistor R17 and connects BP3 to…
Part Number: TPS544B20 Tool/software: Hi team,
May I know the minimum required slew rate of input voltage to CNTL pin? My customer has been evaluating the TPS544B20 by TPS544B20EVM-634. The output voltage rises like saw-like as below when the slew rate…
Part Number: TPS544B20EVM-634 Hi e2e,
Recently, a customer had an inquiry about measuring bode plots at both DIFFO pin and Vout+.
He was wondering if there is any difference between these 2 pins when measuring the bode plots?
Questions:
1. Is there any…
Part Number: TPS544B20EVM-634 Other Parts Discussed in Thread: TPS544B20 , Is TPS544B20 EVM schematic correct? I have TPS544B20EVM-634 Rev.A. I think components value and circuit connection is wrong. The EVM's switching frequency was 250kHz. And TP3 and TP4…
Hello!
If Margining = Low or High then READ_IOUT = 0,
but Vout (and real measured voltage) is ~0.97V
If Margining = None then READ_IOUT = 0.38A (realistic value for connected load),
but Vout (and real measured voltage) is ~1.016V
Is something wrong…
Hi,
I have a question on the output voltage ripple of TPS544c20EVM-634.
The following figure is from "Using the TPS544C20EVM-364, TPS544B20EVM-364, PWR-364 (Rev. A) " (SLUUAY7A).
What is the root case of the voltage platform in red cycle? How…
