Part Number: TPS61165 I am able to PWM @ 10khz Ctrl pin to dim display, this part works fine. But I can not get the one wire EasyScale function to work.
I am using the TPS61165 with an STM32. I have verified each pulse I am sending to the CTRL pin via…
Part Number: TPS61165 Hello,
I am trying to use the simulation model and run a PSPICE for TI simulation with temperature sweeps.
I see the PSPICE model for this part has defined TNOM=27, while the temperature sweeps run for temperatures like 28C 26C…
Part Number: TPS61165 Tool/software: Hi, I am working on yocto scarthgap 6.6 kernel and I want to add support regarding the backlight LED controller (tps61165) in my BSP. Please provide the driver and related things to validate this controller. Thank…
Part Number: TPS61165 Other Parts Discussed in Thread: TPS923611 , Is it possible to use a separate votlage for VIN, instead of connecting it to the inductor? Here is what I am thinking:
Do you think this would work? I don't see why a different voltage…
Part Number: TPS61165 Other Parts Discussed in Thread: TPS61500 Hello,
We are using the TPS61165DBVR for LCD backlight control in a common design supporting two LCD variants:
24 V @ 420 mA (10.8 W)
33 V @ 480 mA (15.84 W)
Both variants…

Part Number: TPS61165 Hi Teams,
We tested the TPS61165 with the maximum current set to 200 mA, using a 22 µH inductor and PWM at 25/50/100%. We observed spikes in the current waveform, with a period of about 5 ms. Is this behavior normal? Thanks.
