Hi Sir,
Yes, 4 LED strings with 2 of TPS61169EVM.
1st LED string connected the IFB1~IFB4, 2nd LED string connected the IFB5~IFB8, used for 1st TPS61169EVM.
Part Number: TPS61169EVM Other Parts Discussed in Thread: TPS61169 , TPS61165 To Whom it may concern :
Currently I am making use of TPS61169 to drive ( single channel ) 6x 6 Leds with Iled 360mA ( application 10.1" LCD backlight driving )
I noticed…
Part Number: TPS61169EVM Hi,
When we connect CTRL to GND to enter shutdown mode, we can still see LED light up a little bit, and the current on LED path is around 5mA. Is it normal?
Thanks!

Customer is evaluating TPS61169EVM for IP Camera flashing application in below spec requirement.
Vin: single cell battery 3-4.2V
Iout: 200mA
LED#: 4
Based on customer's need, we follow…
Part Number: TPS61169 Hi Team,
Our customer would like to use TPS61169 at the following conditions.
[conditions]
-VIN=3.15V
-ILED=20mA
-LEDs=7strings
-PWM = 3.3V, 50kHz, Duty 1% to 100%
So, PWM level(3.3V) is higher than VIN(VIN=3.15V)
Can we use TPS61169…

Hi Team,
We are evaluating TPS61169EVM at the following conditions.
ILED of measurement result does not accord with the calculated value at low PWM duty.
Obviously, we doubt our measurement environment but please let me ask one…
