Part Number: TPS923652 1. As per the buck-boost application diagram in the datasheet, the LED string cathode is connected to VIN and not referenced to ground. Our understanding is that this is a non-inverting buck-boost topology with a floating LED string…
Part Number: TPS923652 Tool/software: Hello,
I’m currently considering using the TPS923652 for an LED application. I understand that the device supports PWM dimming via the DIM pin. However, I would like to ask:
Is there any way to achieve dimming…

Dear Team,
We have used TPS923652 IC in our design for LCD back light control, Rating for LCD backlight are 270mA max current and Forward voltage 9.6V.
As per design followed all the steps, even went through…
Part Number: TPS923652 Tool/software: Use TPS923652 to build a BOOST architecture LED DRIVER. When the LED terminal is short-circuited, there seems to be no protection function? Only the FAULT PIN will be pulled low? (Vin=24Vdc, Iout=0.7A@39~42V (LED…

Hi,
My customer has been using the TPS923652 to drive UV LEDs, and is experiencing failures.
Under no load, they are seeing the device get hot and eventually burn out or experiencing an overvoltage event.…
Tool/software: Hello expert
I set the LED current to 700mA and applied 3.3V to the EN pin. I applied a 20kHz, 50% duty PWM signal to the other adjustment pin. I plan to turn it on and off from the EN pin. Since I want to use four different colors, each…
Tool/software: Hi,
The FAQ list an entry on how to design the COMP Pin components.
[FAQ] How to design the COMP pin components for TPS923655 / TPS923654 / TPS923653 / TPS923652?
But there are two references give, ( Section 7.5 , and Section 9.2…
Part Number: TPS923652 Other Parts Discussed in Thread: TPS92641 Tool/software: Hi Sirs,
I want to confirm the speed at which the LED driver can turn on and off the IRLED current.
Do boost and buck-boost modes have the same performance?
I expect…
Part Number: TPS923652 Tool/software: Dear TI Engineer,
We drive the LED using TPS92365 and use the same signal in both PWM and ADIM modes. When using a frequency of 20KHz in PWM mode, the current control method is to generate a 10s PWM signal and…
