Part Number: TPS92512 I am noticing a significant spike when ever PWM pin is enabled from the disabled state as shown below in figure 1 at upper input voltages around 30vdc. Web bench does not show this anomaly when simulating PWM however the PWM is…
Part Number: TPS92512 Other Parts Discussed in Thread: LM3409 , TPS92515 , Hi All
After turning on the power, I am in trouble that the time(Tdelay) for PDIM to switch from L to H to regulation mode is long.
Is it okay to make Ccomp smaller ? Is there any…

Hi! I have been working on getting a 2A LED driver working using the TPS92512 IC for the past couple of weeks. The circuit does function to some extent (it lights up the LEDs for some time and can be PWM dimmed), but after a short…

Part Number: TPS92512 Other Parts Discussed in Thread: TPS92515 , TPS92641 , LM3409 Hi Currently, our customers are developing the following LED Module using TPS92512.
Vin: 41Vdc, Load: 12 lines Serial (3x12 = 36V)
PWM dimming is changing LED brightness…
Part Number: TPS92512 Other Parts Discussed in Thread: TPS92515 Hi Sir,
our customer based on datasheet page 17 design TPS92512 for 3 LED series Lighting,
if Pin4=3.3V LED turn on LED+ have 8V. but Pin4=GND ILED can't turn of to zero and LED+=7,5V…

Had change different types of inductor to trying get rid of audible noise but still not find solution yet.
- PWM Frequency : 4kHz
- Switching Frequency : 750kHz
Below two photos are output current upon PWM(4kHz) duty.
I can see…

Hello,
Upon attached schematic, audible noise generated from Inductor(L1 and L3) when dimming.
- Using PWM frequency 16.kHz : Barely hearable(Very high frequency noise)
- Using PWM frequency under 16kHz : Hearable. getting louder…
Part Number: TPS92512 Tool/software: WEBENCH® Design Tools hi
i have been trying to use the webench to design with the TPS92512 and i can not seem to use it
even if i start from TI's page of the TPS92512 i can not seem to select it
the device does…
Part Number: TPS92512 Hi,
I have a design with the TPS92512 and unfortunately it has quite high level of flicker when dimming down lower than 100% duty cycle. I wonder the TPS92512/TPS92512HV can be designed to meet the IEEE PAR1789 standard?
Br,
