Part Number: TPS54225-Q1 Hi,
I am currently working on a design and I want to use TPS54225-Q1 to generate 5V rail.
Here are some requirements:
Input: 9-18V; Output: 5V@1A.
I have designed the schematic as following:
Please let me know if you have any…
Other Parts Discussed in Thread: TPS54225 I'd like to be able to connect a few power good outputs from various LDO's and switchers together as they are open-drain. The TPS54225 says to connect the PG to VREG5 pin. VREG5 says it is approx 5V and…
Other Parts Discussed in Thread: TPS54225 Hi,
Please let me ask about internal 5V regulator of TPS54225.
Is VCC input used only for internal 5V regulator? Or is it used for other internal circuit directly?
Can you provide PSRR of this internal 5V regulator…
Other Parts Discussed in Thread: TPS54426 Hi, Could you tell me about TPS54226RGT PKG θjA and θjc? I think generally θjA > θjc. But,datasheet is θjA(46.1) < θjctop(58.1). Please tell me this reason. Or please tell me…
Hi,
I found that the abnormal startup when VIN turn off and on with short interval. Please see following background and give your comment for question.
Background
The normal startup could be seen when VIN is turned on and off with long interval.
But the…

Other Parts Discussed in Thread: TPS54225 Does a Min value have Css of TPS54225?
Although there are worries about inrush current, the customer thinks in tss:200 μs or less (Css:523pF or less).
Thank you for your consideration.
Hello,
Please answer following request from customer.
Datasheet specify that the Current Limit is 2.5A min and 4.5A max.
Customer wants to know the variance of Current Limit.
Could anyone give me the distribution data of Current Limit ?
Best Regards…
