Part Number: TPS22965-Q1
We got a question from customer about TPS22965-Q1.Could you help us?
[Question]They consider to use the IC at 3.3V power supply. But there is not any data in datasheet. Could you provide below data?
- Condition - Vin=Vbias=3.3V
- Data - Ron@1.8A ton toff tr tf td
I will take these measurements and will get back to you by next week.
In reply to Aleksandras_Kaknevicius:
Thank you for your support. I look forward to your feedback.
Hi, We got additional question from customer. Could you help us?
- How much is the recommended maximum output capacitor value? They are concerned about exceeding Tj rating by discharge current. In case of TPS22918-Q1, external resistor Rext is required in Cout>200uF.
Please find the requested data below. This was taken without a CT capacitor.
Let me know if you have any questions.
In reply to tateo yamashiro:
Could you help provide some information on the application for us to determine whether or not this would be feasible? We would need:
The maximum capacitance will vary depending on the above information. Since 1.8A is already close to the maximum current for the device, it may be difficult to support a large output capacitance. In the case, the TPS22965-Q1 would be the safer choice.
Thank you for your support.And sorry for confusing you. They want to know the recommended maximum output capacitor of TPS22965-Q1. I'd appreciate it if you could answer this question.
Hi, I'm sorry I didn't make it clear enough. Their condition is under the below.
Vin=3.3V Iout=1.8A Ta=95C max Desired output capacitor=242uF
They would like to make sure the recommended maximum output capacitor of TPS22965-Q1. They are thinking output capacitor range is limited by Rpd.
Thank you for the clarification. The output capacitance of 242uF should not cause any issues for this application.
Hi, Thank you for your support. We understand 242uF should be ok for their application. And they want to know the recommended maximum output capacitor value. Is there reference value?
