Part Number: TPS92512 Hello,
- Using TPS92512 evaluation board
- Input power to board : 41V
- LED : 12(Serial) * 18(Parallel) LED stack voltage : 36V
Had test full range of PWM duty(0~100%) and getting output(Watt) as expected except one point.
When setting…
Part Number: TPS92512 Hi Support team
Trying to debug this remotely for a customer. I have schematic and can share via email.
They are running at 1.8MHz, VIN-28v, Vout is 7-9v depending on LEDs Vf, current is 0.5A.
they are using a 10uH inductor into…

Part Number: TPS92512 Hi,
There is new project, 24V vin,6 string LED,1.5A,used TPS92512.
Inductance ring when duty cycle < 100%, 100% duty cycle is OK. PWM frequency is 1Khz. when PWM frequency is 30Khz , the inductance does not ring. What advice do…

I am using LED Driver TPS92512 for battery operated street light new design.
No of series LEDs : 3 , LED Srting Voltage is 10V(approx.). The driver is working O.K when the V-in is greater than 12…
Hello Matt,
Those are some good pics. To answer your questions:
1. Yes. Blown bond wires are always due to an overcurrent event, or a series of overcurrent events over time. It could be from PH getting pulled below ground or from shorting PH or the output…
Part Number: TPS92512 I am working on a prototype of a new design using the TPS92512. I was assuming the the ISENSE pin worked as a normal peak current comparator input and expected the voltage to reach a peak 0.300V and shut off the buck switch. What…
