  • TPS922052: PWM pulse width and hysteresis effect with flexible dimming

    Resolved
    Part Number: TPS922052 I have built and have been testing the following circuit based on the TPS922052. I used a draft tool shared with me to compute some of the values, and then looked at the EVAL schematic for further information. I'm putting the chip…

  • TPS922052: Time until FAULT function is executed

    Part Number: TPS922052 Hi, The table below states that the FAULT pin goes LOW when the LED is open, and automatically returns when the open state is resolved. If the LED actually becomes open, how long does it take to determine that it is open and activate…

  • RE: TPS922052: Unable to smoothly fade in/out using Flexible Dimming mode

    Resolved
    Hi Elan, You are welcome. If you take both resolutions of EN/PWM pin and ADIM/HD pin together in flexible dimming mode, there is a chance that TPS922052 can achieve higher dimming ratio compared to TPS92641 when only shunt PWM dimming is used. And you…

  • TPS922052: Is the resolution of analog dimming up to 8 bits?

    Resolved
    Part Number: TPS922052 There is no clear description of the electrical characteristics, so I asked just to be sure. Is the resolution of analog dimming up to 8 bits? (Is this due to the specifications of the internal DAC?) For example, even if FADIM is…
