Part Number: TPS61022
[Update Jan. 1 2022, well the low impedance on SW is due to the low impedance of the supercap of course. I will further investigate and update this post - please do not reply to this post for now!]
Hello there,
I am using the TPS61022…
Hi Craig,
First, thank you for using our product. The TL7660 has an output impedance of about 60 Ohm typical and hence voltage drops. When you have load current, your output voltage will see some voltage drop as shown in the two bottom figures on page…
Hi Alex,
Could you recommend a set-up based on this information?
Since you have on the board are 24, 12, 5, 3.3VDC power rails, I would recommend to create a negative -5V supply rail from switched-capacitor voltage inverter, such as LM2776 , LM27761 , LM26…
The datasheet's layout guidelines say:
Place C IN on the top layer (same layer as the LM2662/2663) and as close to the device as possible. Connecting the input capacitor through short, wide traces to both the V+ and GND pins reduces the inductive…
Hi Dave,
Thank you for consider the LM2663. Yes you external pull-down to operate the device. Most figures in the datasheet apply to both LM2662 and LM2663, so the pin is left open. However, in the Pin Functions table, it is clearly recommended to ground…
Part Number: PGA2311 Other Parts Discussed in Thread: LM2662 , LM828 Hi' All
There was a thread 2 years ago with no solution and I have not been able to find an answer.
I need to run the PGA2311 in a single supply operation for the analog part
So Va…
Hi Ivan,
Regarding the TPA6205A1, where does it indicate in the datasheet that it can use a dual supply? The application circuits are showing a single supply so I'm confused about that.
Do you have a recommendation for a stereo amp so I don't have…
