Hi Amritha,
Please remove the 150kohm resistor.
TPS92641 is a constant-current driver, but not a constant-voltage driver. The current limiting resistor (150kohm) is not needed here.
Best Regards,
Steven
Part Number: TPS92641EVM Other Parts Discussed in Thread: TPS92641 Tool/software: We have bought TPS92641EVM. We wanted to connect a MOSFET to the evalutation board (parallel to the LEDs) as given in the circuit diagram of TPS92641. What is the method…
Hi Archie,
if you are using the default EVM setup with no components changed and power the board with Vin = 12V, then the device will never get out of UVLO. You should change the UDIM resistors. You can refer to Section 7.3.5 Undervoltage Lockout (UVLO…
Part Number: TPS92641EVM Tool/software: In reference to the ongoing case CS2427575, we have procured the TPS92641EVM for building an experimental setup.
To resolve the issue at the earliest, we kindly request a short video conference.
Part Number: TPS92641EVM Other Parts Discussed in Thread: TPS92641 Hi
Can you advise how to modify the schematics to get 12A output?
our LED voltage is 4.5V ~ 5.5V.
Part Number: TPS92641EVM Other Parts Discussed in Thread: TPS92641 Hi team, I'd like to set the output current to 0mA. the bellow conditions, about several mA is output. UDIM : 3V(High) IADJ : 0V(Low) I assume this is because of switching if Vin is present…
Hi Takeshi,
Takeshi Hojo said: ↑Why the datasheet recommend such a capacity(C9:1uF)? The reason is ripple curret to be removed for finely analog dimming?
I think you are referring to Section 4.1.5 from the EVM User's Guide. Although I am not the writer of…
Hi Subahan,
I do not receive any e-mail from you. Where do you send it to? Do you have a TI FAE contact window?
I have just sent you a friendship request on this E2E forum with my e-mail attached. You can contact me there.
BR,
Steven
Hi Steven,Thank you for youre reply.
I'm sorry for lack of explanation and my misunderstanding.
The input voltage(32V) is Vout to the LED of the TPS92641EVM (i.e. Vout in the TPS92641EVM data sheet) LED voltage(35.6V) is the specifications of the LED…
