Part Number: TPS61163 Hi team,
My customer use TPS61163 in their mobile phone project and they use dual channel. When connecting the screen, only one channel work. Only reset the device, dual channels can return to work. Do you have any idea about this…
Part Number: TPS61163 Other Parts Discussed in Thread: TPS61193 , TPS61177A , LP8556 , TPS61187 Can we use direct PWM control method to control LED current in TPS61163?
PWM frequency is 30Hz with 2mS on duty time.
Part Number: TPS61163 Hi,
I'm using TPS61163 on a new design using a 8LEDs per String, 2 String LCD. I see switching at the immediate start or after toggling the enable pin high, but after a few cycles the part seems to be disabled & our 5V input…
Hi Valentinas
Do you want automotive LED boost driver or non-automotive?
8LEDs in series, right? How many channels do you want?
If automotive, you could look at LP8866-Q1;
If non-auto, you could look at TPS61163/4/9...

Other Parts Discussed in Thread: TPS61163 Hello,
The TPS61163EVM used R1 and C4 for the Vin filter. May I know the TPS61163 maximum Iin current(Vbat=3.0V~4.35V)?
What kind of resistor is good for it? 0402 or 0201? Thanks!
Other Parts Discussed in Thread: TPS61163A , TPS61163 Hello, Could you please let me know the difference between TPS61163A and TPS61163? Best Regards, Ryuji Asaka
Hi,
TPS61163 is the BOOST+Current Sink Topology, the current sink will turn on/off with fixed frequency, if you put a large capacitor on the FB pins, it will definitely have big effect on the topology. Because the voltage will decrease very slowly…
Other Parts Discussed in Thread: TPS61163A , TPS61163 1.problem – TPS61163A output voltage is drop. 2.cause – SW voltage is measured OVP level on turn on test with min dimming. TPS61163 OVP -> latch -> LED off -> smart phone LCD off.…
