Part Number: TPS92691 Hi,
We uset the TPS92691 for LED driver c onstant current source, we need to output current is more than 4.7A for the LED driver,
Now, we have production about 5k boards(1pcs TPS92691 per board), and we find there are about 5% probability…
Part Number: TPS92691TPS92691 is a LED controller, not a monolithic IC which has an integrated FET. Hence, I'm curious why the landing page for this part ( https://www.ti.com/product/TPS92691 ) mentions that Iout(max) is 5A. It was my understanding…

Part Number: TPS92691-Q1 Other Parts Discussed in Thread: TPS92691 We are investigating using the TPS92691 in a buck-boost topology. The power supply that we are using to power the LEDs is 48 V. We need between 36.4 V and 52 V out. I will note that we…
Alexander,
If the design has worked before then it's usually workmanship or assembly issue. Glad to hear that you have resolved your issue.
Thanks Tuan
Part Number: TPS92691 we use TPS92691 to driver laser diode for DLP project, the input voltage is 19.5v and output voltage is 48v and current is 3.0A。
we measured that the rise timing and fail timing of TPS92691's output is out of spec of DLP system requirement…
Hello Jiawei,
In general, the TPS92692 is a TPS92691 with a few additional features listed below:
1. More comprehensive FAULT detection and Fault Flag indicator
2. Programable Slope Compensation
3. Spread Spectrum Modulation
4. Internal Voltage to PWM…
Part Number: TPS92691 Hi,
We use the TPS92691PWPR for our new deisng and there are some issue as below:
1. We use the boost topologies that the input voltage is 24VDC and output voltage is 27V, and then, we use the Rcs=0.035ohm, the output current is 4.7A…
