Part Number: TPS7A78 Dear team,
My customer was considering using TPS7A78 for their AC to DC power supply. But the requirement of output current is changed up to 300mA. But output current limitation of TAP7A78 is up to 120mA.
Is there any solution to…
Part Number: TPS7A78 Hello,
I'm using the TPS7A78 part in FB mode to power digital circuits; in this case GND is not connected to AC-(Neutral) line. The GND line is tracking the AC- line, which could be the hot or neutral line and so far using the demo…
Part Number: TPS7A78 Team,
1)I am looking at the below use case: 24VAC VIN -> 12VDC Vout
It seems that SCIN can be used as output. What would be the max current that could be sink from SCIN. The idea would be to use an LDO on SCIN to get 12VDC and not…
Part Number: TPS7A78 Hi Ti
The TPS7A78 looks ideal for an application we have for a wireless device where we have previously used a cap dropper circuit or a cap dropper followed by a buck converter (TPS54601).
I'd just like to clarify the device efficiency…
Part Number: TPS7A78 Hi Sir,.
please help to check
(1) What is C6 , R5 voltage rating and what is footprint should I use for this AC/DC application
(2) Should I incluse some circuit protection in the front of Full bridge recitifier or not.
(3) For the…
Part Number: TPS7A78 Hi, Let me confirm the operating principle of TPS7A78. ① DC cut with Cs → Voltage drop with Rs ②Fit within 30V input range ③Input a voltage such as half-wave rectification to the AC+ (AC-) pin, and output the voltage at a low voltage…
Part Number: TPS7A78 I have two questions:
When is the TPS7A78 scheduled for full production? I have a new circuit design here, and I would like to use it. But my customer wants to be sure that the TPS7A78 will be available within the next few months…
Part Number: TPS7A78 Hi
My customer have some questions regarding TPS7A78EVM waveform.
We change the AC input voltage from 80VAC to 240VAC and find the value of SC IN and AC+ voltage is constant.
however, the [H] duty of SCIN begins to decrease when…
