Part Number: TPS62823 We are looking in confirmation of the circuit correctness which is requested by seniors. Kindly do the needful if anymore information required feel free to ask.
Input supply is with in the module, which can support 3.3V @ 2A, Case1…
Thanks davon
Total output capacitance on the line is around 250uF
I think that was the reason of the glitch as you pointed out. Haven't got time to chek removing capacitor and see the result.
But now in the next design revision we are using LM5141…
Part Number: TPS62823 Other Parts Discussed in Thread: TPS62825 Hi Team,
we have designed in TPS62823 in an application where the high output current actually is not needed. With this we see the regulator operating in discontinuous conduction mode and…
Part Number: TPS62823 Other Parts Discussed in Thread: LM3881 Hi,
We're having some issues with a design with the TPS62823. Before the very first power on of a board, impedances seem to be ok, but after the first power on, a short has developed between…
Part Number: TPS62823 Hello team,
I got a question from the customer.
Could you please tell me the FB voltage accuracy during the PSM?
The DS mentioned, "output voltage rises slightly above the nominal target". The customer would like to understand how…
Part Number: TPS62823 I'm using a TPS62823 in a 5V to 3.3 V step down application. In our application the power input input cable is very long and when plugged in we see an 8V transient as measured at the input capacitor:
Obviously this exceeds the…
Part Number: TPS62823 Hello team,
Would you mind telling me why the external 100k resistor is added VIN to EN?
I assume that the EN pin has an internal resistor, and the small current is always going through it if there's no external resistor.
This…
Part Number: TPS62823 Hi,
My customer find the EN pin drop waveform at power up.
Could you please let me know the reason of this behavior.
It is occurred before Iout rising timing and Switching start timing. They cannot find Vin drop.
Does TPS62823 EN…

Hi Expert,
My customer have a question about SW node absolute max.
They found the following waveform that is over voltage Vin+0.3V(ABS MAX) on SW node and over 10ns.
Also, It seems, Body diode of High side FET turned on, becaus…

Hi,
I am looking for a step-down converter to meet the following requirement: Vin=5V; Vout=1.8V; Io(max)=3A; Vripple=5mV; load transient…
