Part Number: TPS92512HV Dear Sir/Ms.
My customer asked me if the action of TPS92512HV OTP is whether the chip temperature reaches 165 degrees, it will be turned off directly (100%→0%), or the current will decrease proportionally (100%→??%→??%→0%) What…
Part Number: TPS92512TPS92512 LED driver, our customer's existing case, may need high-frequency PWM dimming (maximum 20KHz). Please help confirm, this IC maximum support PWM dimming frequency to how many Hz.
Part Number: TPS92512 Dear TI Experts,
Our customer used TPS92512 as LED controller in their products,
and they found that when TPS92512 work in the low frequency the voltage ripple is very high, when TPS92512 work in 12Khz, the voltage ripple is ok; …
Part Number: TPS92512 Other Parts Discussed in Thread: TPS92515 , TPS92640 , LM3409 hi,
i am using TPS92512 ,for dimming purpose
i am using 24v supply and 4 X20 led matrics (4 series)
i get the flickering during the period when current in between 600mA and…
Part Number: TPS92512 Hello
Customer used TI/TPS92512 for LED driver control, Since they need to drive 0.7A current for LED control. Could customer used 250 Hz for PWM frequency design ? Thank you.

Hi Team,
We are having an issue adjusting the LED current when trying to vary below 200mA.
We use a TPS92512 LED Driver(I will email schematic offline). In this case (R308 =0.1 Ohm), at the lowest output of DAC (U301), the voltage…
Part Number: TPS92512 Tool/software: WEBENCH® Design Tools Thank you Atul
so the VIN parameters are the problem,
since i was planning on using the car battery (12v) and when i insert those parameters TPS92512 is not there
does that mean that it is not…
Part Number: TPS92512 I have the TPS92512 set up almost identical to the set up created by web bench except that
1. I and enabling the unit via 0-5v pulse into PDIM. For the purpose of trouble shooting this is currently a constant 5v as soon as the micro…
Part Number: TPS92512 I need to dim a LED module that uses a TPS92512DGQR but I can't use the built in pwm pin. I am only allowed power and ground lines to the device. The power signal will be PWMed at 100hz between 15% and 100% duty cycle. I have…
