Other Parts Discussed in Thread: TPS54229 Hola,
I have a question about feedforward capacitor for TPS54229.
Below description is from TPS54229EVM user's guide：
My question is that, why it's only 1.8V or above needs feedforward capacitor but under…
Other Parts Discussed in Thread: TPS54229 , TPS562200 , TLV62084 Dear all.
Our customer needs less than 2MHz switching frequency of device. (Please don't introduce other devices because not approval of customer's side.) In VIN=3.3V of "Figure 8. Switching…
Other Parts Discussed in Thread: TPS562201 , TPS54229 Hi Sir,
I had run a simulation on Webnech with TPS562201 and TPS54229, I thought that the TPS562210 should have a better efficiency since it have lower Rds on and the schematic is the same.
But the result…
Other Parts Discussed in Thread: TPS54229 Hi
My Customer has questions.Please tell me.
In order to determine the minimum input voltage, We got two questions.
We hope to cooperate.
Q1:How much SW Frequency of min & max ?
Q2:How much minimum OFF Time…
Other Parts Discussed in Thread: TPS54229 Hi,
Please let me ask about Figure 13. VFB VOLTAGE vs JUNCTION TEMPERATURE in datasheet of TPS54229.
Can we consider the Ta=25degC for this graph? Or is the description of Ta=25degC is applied for this graph?
Best…
Hi,
The VFB accuracy at Ta=25degC is stated in datasheet but now our customer hope to know it over Tj range as just for their information. Do you have any information you can disclose? We and customer understand that you can not guarantee the information…
Hi
The Dual TPS54283 is dual output device. It will be more expensive.
Did you look at the TPS54229 and TPS5620x devices?
The TPS563201 and TPS563208 are simple, easy-to use synchronous back converters is SOT package. Input Voltage Range: 4.5 V to 17…
Thank you for your answer!
For example,
UVLO threshold of TPS54202 is written with VIN.
But TPS54228, TPS54229 and TPS54628 are written with VREG5 about UVLO threshold.
We want to know the UVLO thresold in VIN instead of VREG5.
Can you define UVLO…
Hello Jacky,
Is it possible that you mean with load current the current that is flowing into the MIC5207 or TPS54229? If this is the case, we call this supply current because it is supplying our IC.
If you mean the current going into the MIC5207 or TPS54229…
Other Parts Discussed in Thread: TPS54427 , TPS54229 , TPS54329 Hi Sir,
I know "Soft-start control. An external capacitor should be connected to GND", but if I pull SS up to VREG5 externally and directly, is there any risk, is it harmful to the chip…
