  • TPS28225: IC FET dead issue

    TI Thinks Resolved
    Part Number: TPS28225 Hello experts, Currently my customer designed our TPS28225 for their refrigerator peltier project and has been in production for a few years. Recently, they've seen an issue where LGATE pin goes dead. Could you please share your…

  • TPS28225: Minimum switching frequency for the TPS28225

    TI Thinks Resolved
    Part Number: TPS28225 Tool/software: Dear all We try to use the TPS28225 at low frequency (1KHz) . It seems that the low frequency limit is above 2KHz, we are unable to make the device working at lower frequency. Could you confirm this? If yes …

  • TPS28225: TPS28225

    TI Thinks Resolved
    Part Number: TPS28225 Tool/software: Hi, I have this issue which is somehow related to the driving method of the PWM input of TPS28225 . As a background, we are using a PWM output from STM32 of 240kHz at a duty cycle of 10% to 18%. Thus, 3.3V PWM levels…
