Hi Neo,
I had to dig around some archives, but I was able to view part of the internal circuitry. Yes, there is a fast feedback loop so the load transients will be more accurate than the bode plots when assessing total system stability. As I mentioned…
Part Number: TPS74401 Hi there,
For validation I need to adjust the feedback voltage divider (R1) in small steps (Vout +- 5…10%) with a mechanical rotary switch resp. different given resistors (matrix) when no load is connected.
Would you recommend…
Part Number: TPS74401 Hi team,
My customer used to apply 100nF of bypass cap on EN pin of TPS74401. It basically functions filtering, I believe not an essential component. They are going to delete this bypass cap for the future design. Do you see any…
Part Number: TPS74401 Hello Expert, I have question for Vbias consideration. My customer plat use this device under following conditions. Vin = 2.4V Vout = 2.2V Vbias = 4V My understanding for Vbias consideration is there are 2 criteria. First is Vout and Vbias…
Part Number: TPS74401 Hi team,
Would you help me for customer schematic review? The current design is as below :
Vin = 1.15V
Vout = 1V
Iout = 1.49A
Vbias = 5V
I was concerning about small Vin-Vout, only 150mV. But it seems the figure 6 is applicable…
Part Number: TPS74401 Other Parts Discussed in Thread: TINA-TI Hi TI experts,
The simulated noise density spectrum is quite different from that shown in datasheet (Fig. 13). The .TSC file is attached below. In addition, I used "select control object" function…
Part Number: TPS74401 Tool/software: WEBENCH® Design Tools Is it feasible to use the PG of the first tps74401 to enable the EN pin of the second tps74401 to control the power on sequence?
show as the follw schematic
Part Number: TPS74401 Hi team,
A customer is using TPS74401 ADJ LDO in his design..
He have some question on description of datahsheet.
In the datasheet they mention that The enable threshold is typically 0.8 V and varies with temperature and process variations…
Part Number: TPS74401 Hi team，
I see in datasheet， the pull-up resistor recommend from 10k~1MΩ，and customer now use a 4.7kΩ pull-up resistor and connect to 1.1V.
Will this bring any problems？Is the 4.7kresistor OK for application？
Part Number: TPS74401 Tool/software: WEBENCH® Design Tools Hi Webench-Team,
I got customer feedback regarding an error in Webench. Can you have a look at it to solve it?
For the TPS74401, Webench behaves contrary to the data sheet. At the lower feedback…
