Part Number: TPS61220 Other Parts Discussed in Thread: TPS61099 While testing the TPS61220EVM-319 I ran in the following issues:
1. When I pull the EN-Pin to GND, the board still puts out ~0.9V on VOUT. I'd espcet to see 0V. The Eval board went through…
Other Parts Discussed in Thread: TPS61220EVM-319 , TPS61220 , TPS61200 We replaced the resistors on the TPS61220EVM-319 with R1=1600 ohms and R2=510 ohms. We used a Keithley 2400 as a voltage source of 2V and a compliance current of 5 mA, which should…
Other Parts Discussed in Thread: TPS61220EVM-319 Hi,
Are the TPS61220EVM-319 gerbers available for download? Or is there a mechanical drawings available with header location?
Thanks

Part Number: TPS61220 I am evaluating a prototype using TPS61220. Vout has a lot of noise. Please refer to the attached document and tell me how to solve the problem. TPS61220DCKR(TI) question.pdf
Part Number: TPS61220 Tool/software: Problem
I'm seeing unexpected voltage output and fluctuating current input on the TPS61220 that I've soldered on my custom PCB (details can be found below). I would kindly request help to debug what might be going…
Part Number: TPS61220
The output is powering a backlight for a display (part number: COM24H2P39ULC from Ortustech). After noticing that the display suddenly blacked out and came back on randomly, I found that when I touched the feedback resistors…
Hello Luke,
You need to Remove SC-70 6-DIP adapter because if you are using this means you places C1 and L 4.7uH inductor so far from the TPS6221 Booster IC so , if you are placing C1, C2 and inductor L1 so far from booster then voltgae drop is possible…
Other Parts Discussed in Thread: TPS61220 , TPS61220EVM-319 , BQ25504 , TPS61200 I am working on piezoelctric energy harvesting, am using TPS61220 to provide constant DC supply to the battery. The output from the piezo transducer is given to bridge rectifier…
The likely issue is breadboarding the IC. As explained in the datasheet, these ICs require a very specific, very compact layout which cannot be achieved on a classic breadboard with through-hole components. The best way to evaluate these ICs is on our…
