hello, according to your loss formula, the result 9.72W should be the loss of the 9 LEDs.
And you mentioned that no thermal pad on the bottom, I suppose your concern is the loss dissipation and thermal condition of IC itself? rather than the thermal condition…
Part Number: TPS61169 Other Parts Discussed in Thread: TPS61500 Dear Sirs and Madams,
our customer like to change the display type in his system, so I have to check the feasibility. I would appreciate your help: is that possible to drive the backlight…
I re-laid out the circuit board with the feedback resistors next to the driver, as you recommended. I also added a second supply bus to better connect the drivers to the supply. These changes did not solve the problem. I tried larger feedback resistors…

Hi,
Do we have a PSpice example project for the TPS61169 EVM? Our customer is having some trouble getting the simulation to work, and it might be easiest if someone already has a PSpice project defined for the EVM.
Thanks, Darre…
Part Number: TPS92360 Other Parts Discussed in Thread: TPS61169 , The datasheet of TPS92360 is highly similar to TPS61169. Not just the pin function, also the details numbers in the specification and circuit.

Part Number: TPS61169 HI team,
I need confirmation on the Control Pin of the driver IC.
I have a processor whose output levels are 1.8V , which is connected to control pin of the driver.
Will this 1.8V levels will be sufficient for the proper operation…
Part Number: TPS61169 Dear TI Team
I would like to confirm the output current regulation of TPS61169. The TPS61169 web page states that the Current per LED value is 400mA, but the electrical characteristics of the data sheet do not have a parameter that…
Part Number: TPS61169 Hi team,
Can you have look at the following customer inquiry please?
In a current project I used the TI TPS61169 to drive a display backlight. The driver worked without problems in the pre-series, but currently we are struggling…
