Hello,
I am designing an LED driver using the TPS92641.
The specifications are:
Vin = 49 V
Imax = 2.1 A
LED voltage = 12–48 V
Analog dimming down to 0%
The design is working; however, I noticed…

Tool/software:
Dear Sir,
which is lower then 3.05V,(an internal reference), it can't work!
So can you give me some suggestion or other choice?
Part Number: TPS92641 Dear Team,
My cosutomer is designing the applicaiton circuit of the TPS92641. They consider to use the External Shunt FET PWM Dimming feature, and consider the layout of QSDIM and Cout. They think to set the Cout as 20uF + 0.1uF…
Part Number: TPS92641 Tool/software: Hi, I am using your TPS92641 to drive a laser. When I use the SDIM pin to dimming the light with PWM, there is an overshoot at the rise of the current waveform as shown in the figure below. I think this is caused by…
Part Number: TPS92641 Dear Team,
My customer is evaluating the TPS92641 application by modifying the TPS92641EVM. They increase V_IADJ from 0V to 2V (for V_CS=0.2V, ILED=5A). When ILED exceeds around 1A, on time becomes random or oscillalting. After…
