Part Number: TPS61199 Hello,
I am using the TPS61199PWR for the backlight. The display's LEDs sometimes blink and when I probed the VOUT, i observed a voltage drop of about 3.2V. I added some output capacitors and changed the ISET resistor from 11k…

Part Number: TPS61199 Tool/software: Hi
The customer's screen has a set brightness level. When the screen brightness is set to level 0, and the screen is turned off and on again, the screen brightness will be brighter than level 0, but darker than level…
Part Number: TPS61199 Hi, I am currently using the Design Tool for the TPS61199 LED Backlight Driver and I wanted some clarification how the gain margin gets calculated in the design tool. Usually gain margin is difference between 0dB and the gain where…
Part Number: TPS61199 Hi Team,
Customer have some questions in design and need support team to comment :
If the input frequency of the PWM pin exceeds the range of 100 Hz to 22 kHz defined in the spec such like using 32KHz PWM dimming, will there…
Part Number: TPS61199 Hey LED Driver team,
I have a customer prototyping with the TPS61199 for a new project and they would like to be able to select different backlight configurations via GPIO and as such would like to use a GPIO to disable unused…
Part Number: TPS61199 Hi，
When using TPS61199, I found that the actual current did not match the set ISET current, the difference was 5 times.
If the ISET resistance is set to 50mA, the single-string LED current measured with a multimeter is only…
Part Number: TPS61199 Hi everyone,
I am writing to you because I have a problem with a new project that I am developing. following the instructions in the datasheet I made my circuit, but I have a problem, the LEDs on my LCD panel are flashing, the…
