Part Number: TPS563257 Hi all,
Please help me review this schematic:
And I have some questions:
1./ With L and output cap, Does it make sense?
2./ If i should install CFF, instead of DNI CFF?
Sincerely,
Van
Part Number: TPS563257 Hi team,
I am evaluating TPS563257 and have a question about an unexpected behavior.
Setup:
Device: TPS563257
EN pin driven by FPGA GPIO with an external 2 kohm pulldown to GND
EN pin is probed at the IC pin and confirmed…
Part Number: TPS563257 Hi Team,
The TS563257 Vout will drop a lot if the loading attached even just 10mA.
Without attached loading, the Vout is no problem.
The Vin is from battery of 4.2~6V and Vout is 3.3V/1A
Please help to check the scematics…
Part Number: TPS563257 Hi
I am reviewing the datasheet of the TPS563257, and I have some questions about the POWER START UP time.

Part Number: TPS563257 Tool/software: Hello guys,
One of my customers is considering using TPS563257 for their new product.
At this moment, they have the following question. Could you please tell me you reply?
Q. R3, 51ohm is inserted to feedback…
Part Number: TPS563257 Tool/software: Hi,
As shown in the figure below, under the following conditions the TPS563257’s estimated maximum switching frequency is around 900 kHz.
So will the TPS563257 automatically reduce its operating frequency from…
Part Number: TPS563257 Tool/software: I just installed Pspice for TI; it wont open some project files (with schematics) I created from several months ago in a previous version of TI Pspice.
A window pops up and asks if I want to convert them to the…
Part Number: TPS563257 Tool/software: Hi all,
I would like to ask about the handling of the PG pin.
If I don't use the function of Power Good, can the PG pin be open?
The datasheet did not show that they are open and used.
Do they need to pull…
Part Number: TPS563257 Tool/software: Hi,
We found peak voltage is too far away from the normal targat value during load transient. Using larger output capacitor can help it.
My question is what measurement should we care during a load transient test…
