If I need 75mA current for LEDs, What's the external resistor ? Is Rest=200mV/75mA=2.85Ω?
There is a Iout_max in spec. If I need output voltage 25.38V, Is Iout_max =167…
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?
Best regards,
Hideki …
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?

Team,
-Can you please confirm if the different below GPNs can be use as P2P dropped-in replacement? -What should be done in the schematics/PCB in order to use them intercheangibly…
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…
Part Number: TPS61161 Hi TI Expert,
I need to consult about TPS61161. If PWM DIM is used, the DIM frequency stipulated in the manual is 5khz-100khz.
1. Is there any requirement for the duty cycle of the waveform? After all, this pin is still the function…
Part Number: TPS61161 Hi Team,
