  • 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…
