  • TPS61169: TPS61169

    TI Thinks Resolved
    Part Number: TPS61169 Other Parts Discussed in Thread: TPS92380 Dear TI support team, I wanted to raised a question about the TPS61169. In the datasheet, it is explain that the minimum dimming value is 1%. We are trying to design a circuit that goes further…

  • RE: TPS61169: TPS61169 - Feedback voltage tolerance and LED current for different dutycycle

    hi Saranya after checking, we only have Vref data available which is also shown in the datasheet 188mV-220mV, and this is valid in the temperature of 25deg-125deg.

  • RE: TPS61169: PSPICE MODEL FOR TPS61169: PMW DUTY CYCLE TUNNING DOESN´t WORK

    Hi Mason. However when I use those devices are actually ideal devices. I cannot find where to edit ESR or anything else. When I checked the Pspice models for those components, they are part of the TPS61169. The components you said are default components…

  • RE: TPS61169: TPS61169

    So right now for 61500, the problem is that you cannot buy due to out of storage online? For other integrated Fet products, it seems cannot satisfy the thermal requirement.

  • RE: TPS61169: TPS61169 current too high; does not respond to value of feedback resistor

    Resolved
    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…

  • TPS61169: PSpice example for EVM

    Part Number: TPS61169 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…
