  • RE: TPS61500: The design issu for TPS61500

    Hi Liang, I have setup the EVM with similar condition, the IC still works normally. May I know if customer could also send me their layout for double check? You can send it to me through private message if customer has confidential concern. BR Patric…

  • TPS61500: Calculations review

    TI Thinks Resolved
    Part Number: TPS61500 Tool/software: Hello Support team, I am going to design backlight driver for 14.5-inch display to supply current to WLED Backlight consists of 5 strings with 8 LEDs for each string. The backlight has common anode and common cathode…

  • TPS61500: Can TPS61500 work in PWM dimming mode with EN pull up to high?

    Part Number: TPS61500 Tool/software: Hi champs, My customer has been using TPS61500 in PWM dimming mode with a PWM from MCU connected to EN pin. In the new design, they are considering to cancel the MCU, and they do not need any dimming. Can they just…

  • TPS61500: TPS61500

    Part Number: TPS61500 Other Parts Discussed in Thread: TPS61169 , , TPS92360 We have a 3V (700mA) LED, which needs to be modulated from 100Hz to 2MHz with a 50% duty cycle (square wave). I wannted to enquir if the above driver (TPS61500) will work. Also would…
