  • 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…

  • TPS28225: Can TPS28225 be used to drive latching relays

    TI Thinks Resolved
    Part Number: TPS28225 Other Parts Discussed in Thread: DRV8411 Tool/software: I plan to use TPS28225 to drive latching relays. Can I achieve it using this part or maybe i should opt for other driver like DRV8411

  • TPS28225: TPS28225 used for tec operation

    TI Thinks Resolved
    Part Number: TPS28225 Tool/software: Hi, I am using TPS28225DRBR to control TEC, below is the circuit i have created, I am able to make the lower temperatures but not the higher ones, means HOT is not working. is this resister wrong at Lgate pin?…
