Part Number: TPS61161 Dear team,
We checked the Datasheet of TPS61161, there’s a question about the Operating Junction Temperature of the TPS61161, why the min temperature is 40℃, not the -40 ℃？
Is it a mistake of this datasheet? Seems the -40℃…
Part Number: TPS61161 Hi experts,
TPS61161 current limit is 700mA but there are description that LED current per channel is 20mA in product folder in TI.com
Is there other ristriction than limitation of N-ch MOSFET current limit?
Part Number: TPS61161 Hi Team,
My customers now use TPS61161 and found it has ripple interference in image sensor because the ripple phenomenon follows this IC.
the frequency of interference is about 600KHz, the schematic can be roughly referred to the…

Part Number: TPS61161 Hi Expert,
In the TPS61161 datasheet, the Ip calculation is like below. While my calculation result is "-Vin" instead of "+Vin". Could you double check if there is anything wrong on the datasheet?
Part Number: TPS61161-Q1 Hi Ti E2E,
Due to TPS61161-Q1 has a soft start built-in IC, the Vout at SW may have two step ramp up behavior at system power up.
I am wondering if there is any risk for give PWM signal to CTRL pin first then turning power rail…
The reason that non-square waveform results in failure is complicated and it's related to the device internal logic circuit. There won't be issues as loog as you utilize TPS61161 according to datasheet.
Part Number: TPS61161 Hi support team,
After using TPS61161 for half a year, the LED started blinking. The resistance value between the FB pin and GND is 11.6Ω. Is TPS61161 damaged and short-circuited?
Please let me know if there is such a precedent…
Part Number: TPS61161 Hi Sirs, My customer is asking a question which needs product line's suggestion: According to the equation in datasheet, VFB = Duty * 200mV, VFB is linear with four LEDs in series, LED current = 20mA with Rset = 20ohm or 10ohm. …
