  • TPS92513, TPS92511 / Dimming Ratio

    Resolved
    Other Parts Discussed in Thread: TPS92513 , TPS92511 Hi, I'm recognizing that we must use PWM dimming to achieve dimming ratio 100:1 by TPS92513. In other words, dimming ratio can't achieve 100:1 by analog dimming only. And TPS92511 can achieve…

  • RE: TPS92511 in boost configuration

    Resolved
    Those might work ok. But this device regulates LED current by monitoring switch current. So in these cases you would actually be regulating the input current. If the input voltage is solid and the LED string voltage is solid that might be ok. But the…

  • RE: TPS92511 Ripple Current

    Resolved
    1. The maximum practical limit is probably around 2.2mH. Any higher and the cost and size would probably become unreasonable. 2. There is no limit to the output capacitor value, but output capacitors slow the rise and fall times of the current waveform…

  • TPS92511 standby current / shut down current

    Other Parts Discussed in Thread: LM3407 Hi, I want to ask why the standby current is so high(2.3~2.7mA)? Is Main switch turnd OFF by turning off VIN? If yes, I can save current to 0.1~1uA only by turning off VIN? Are there any other method to…

  • PWM dimming limit for LED Driver(Base on TPS92511 Application)

    Other Parts Discussed in Thread: TPS92511 , LM3402 , LM3404 , LM3406 Hi All, I have question of PWM dimming limit for LED Driver(Based on TPS92511 Application), 1. The TPS92511 has very fast PWM dimming response time. For example, if the switching…
