  • TPS92520-Q1: CSN Protection Diode Recommendation

    Part Number: TPS92520-Q1 Hi, Team For TPS92520 circuit design, datasheet recommends to use a Schottky diode to protect the CSP / CSN node. “A Schottky diode with low forward voltage drop at room-temperature and nonrepetitive peak surge current rating of…

  • TPS92520-Q1: Output open circuit Fault detection time threshold

    Part Number: TPS92520-Q1 Hi, Team What is the time threshold for output open circuit fault detection of TPS92520-Q1? In other words, how long can an output open circuit fault state be maintained to ensure that it will be detected? What's more, I understand…

  • TPS92520-Q1: Open detection issue

    Part Number: TPS92520-Q1 Hi Experts, Customer concern about output open circuit detection. The thing is that the output of this IC show a waveform. (like sin wave, Max 51, Min 40~43) So they concern if the open detection mechanism detect the minimum value…

  • TPS92520-Q1: TPS92520 External Components Parameter Calculation Tool

    TI Thinks Resolved
    Part Number: TPS92520-Q1 Hi expert, Do we have a calculation tool like Excel for TPS92520's external components parameter calculation?

  • TPS92520-Q1: Synchronous mosfet and 16:1 dimming range

    TI Thinks Resolved
    Part Number: TPS92520-Q1 Hi Experts, I have poor knowledge about synchronous FET Dimmig. I don't understand about "dimming range of 16:1". Could you please explain about this? In data sheet, 7.3.6 Analog Dimming and Forced Continuous Conduction…

  • TPS92520-Q1: Output clamp diode questions

    TI Thinks Resolved
    Part Number: TPS92520-Q1 Hi Team, Could you possible help to check if customer could remove the output clamp diode which we recommend in datasheet? Since currently, customer with 100nF output capacitor and with 7m cable from LED+ and then short the cable…

  • TPS92520-Q1: Can two buck output of ONE TPS92520-Q1  connect together to supply one LED load?

    TI Thinks Resolved
    Part Number: TPS92520-Q1 Hello, There are two buck in one TPS92520-Q1,if we connect the two output together, is there any risk? On my view,when the MOS of buck1 is ON,and the MOS of buck2 is off, there may be current flow from MOS and power coil…

  • TPS92520-Q1: Should we must use input undervoltage protection?

    Resolved
    Part Number: TPS92520-Q1 I mean just use MCU to directly control the UDIM pin for ON/OFF. but if unfortunately have a very noisy input such as a 12V with 3V 1KHz ripple, then some ripple on Boost (VIN for TPS92520) and on V5D. Is there any risk? What…

  • TPS92520-Q1: Can 92520 discharge the output capacitor if we don't add the discharge resistor when power off?

    TI Thinks Resolved
    Part Number: TPS92520-Q1 If we don't add output resistor in parallel with the Cout. When power off, will the output voltage fall slowly and the LED keep on for some time? Or if 92520 has built in discharge circuit to discharge the CAP? If yes, where…

  • TPS92520-Q1: External PWM operation

    TI Thinks Resolved
    Part Number: TPS92520-Q1 Hello, I would like to know if using the external PWM can only be done if the device is in standalone mode. Does it mean that the PWM switches ON/OFF the device based on the by changing the UDIM input and act as enable signal…
