Part Number: TPS7A74 Dears Experts,
We are designing a power supply using TPS7A7401 with an input voltage of 1.8V, an output voltage of 1.5V, and an output current of approximately 1A; When testing Vbias=Vin=1.8V, the Vout output is only about 1.1V;…
Part Number: TPS7A74 Hi,
I saw the discussion on using FB for remote sensing. I'm thinking of using a feed-forward capacitor after seeing it. However, my application involves a board-to-board transition as the load is in a different board. Is it better…
Part Number: TPS7A74 Tool/software: Hi Team,
I am using the TPS7A7401DSDR part for Vin=1.8V & Vout=1V with Bias Voltage of 3.3V, Iload=1A
While checking for the drop out voltage, the condition fails for my case. so what would be the required drop…
Part Number: TPS7A74 Tool/software: Hi support team, I am considering using it with the following specifications:
VIN = BIAS = 3.3V VOUT = 1.8V IOUT= 0.5A
Based on the specifications below, will a BIAS voltage of VOUT+1.5V be sufficient?
From…
Part Number: TPS7A74 Tool/software: Hi Team，
The customer reported that the measured case temperature of TPS7A74 is 90℃. If RθJC(top)=55.3℃/W is used, the junction temperature is about 124℃. Is this expected? In addition, can you share a guide, including…
Part Number: TPS7A74 Hi Team，
It is known that the case temperature (Top) of TPS7A7401 is 117°C. Should ΨJT or RθJC(top) be used to calculate junction temperature? From the datasheet, I see that ΨJT is smaller than ΨJB, which is different from RθJC…
Part Number: TPS7A74 Other Parts Discussed in Thread: TPS74901 Hi Team,
Customer report that when the load (electronic load) is set to CC mode 2.7A, the device restarts repeatedly and the peak output current is as high as about 8A. This appears to be…
Part Number: TPS7A74 Other Parts Discussed in Thread: TPS7A57 , TPS61299 , TPS7A57EVM-056 , TPSM82903EVM , TPS62122 , TPS62120 Is there a part like TPS7A74 but without VBIAS requirement that can do VIN 1V1, VOUT 0V9 and current 1A or more?
So far I…
Part Number: TPS7A74 Hi team,
1. does lower bias voltage leads to lower power consumption ?
2. my customer Vin is 1.8V, if we connect Vin pin to bias pin which minimum is 1.7V,
is there a risk? what would happen if it somehow drop to 1.7V
…
Part Number: TPS7A74 Hi Team，
Could you pls help review the schematic, and I have 2 questions here:
1, What's the risk of having a capacitance greater than 15nF on the SS pin? Could you please clarify.
2，I think a capacitor to ground helps reduce…
