Part Number: TPS61165 Tool/software: Hi,
My customer is looking for an LED driver to interface with Winstar's WF0200BTYAJDNG0. They were considering the TPS61165, are there any improvements or issue you might see with it? They use this on backlights…
Part Number: TPS61165 Other Parts Discussed in Thread: LM36010 ,
Tool/software:
We are working on a slave flash design in which a photodiode will detect a main flash and send a signal to a mcu which will then activate our LED flash. I have been researching…
Part Number: TPS61165 Tool/software: Hello, we need to know if the Rset calculation estimate for the LCD backlight is correctly calculated. We are using the circuit in the image below.
Please, could you verify if the feedback resistor is properly…
Part Number: TPS61165 Hi ,
We are using TPS61165DBVR LED Driver ,
When applying the Vin = 5V, 0.5A, PWM 50KHz to the LED driver ic, i am getting same 5V across the LEDs, the output voltage is not boosted.
Please clarify what was the wrong
Regards…
Part Number: TPS61165 Other Parts Discussed in Thread: TPS61169 , Tool/software: Power source: Lithium-ion battery (3.7V, 3000mAh) LED: IF = 700mA, VF = 1.8V (3 LEDs connected in series)
I plan to use a battery as the power source. Could you recommend…
Part Number: TPS61165 Tool/software: Hi Team,
1. What is the maximum receive current specification for this driver IC? 2. According to datasheet the current limit is 1.2A. When exceeding this current, will the LED driver shut down? If not, when input…
Part Number: TPS61165 Tool/software: Hi team,
We are using a pin which can be controlled either as GPIO or PWM to control the LED Driver.
When we drive it as IO and make it High, the output voltage of the driver is around 12V with display connected…
Part Number: TPS61165 Tool/software: Our SDR design uses the TPS 61165DRVR to drive the LED backlight on the LCD used to display the frequency spectrum, it is powered by the 13.8V input, we carefully followed the TI design guide and PCB layout.
Problem…
Part Number: TPS61165 Tool/software: The frequency range that can be set from the data sheet is 5kHz to 100kHz.
Is it possible to set the duty ratio to 1% to 100% throughout this frequency range? (Does the duty ratio that can be set change depending…
Part Number: TPS61165 Tool/software: Hi Sir,
My customer used the TPS61165 for the backlight dimming application.
Only the PWM dimming duty at 100%, the dimming function is working normal.
The dimming function is working abnormal when the dimming…
