    TPS62170DSGR Frequently Asked Questions (FAQs)

    • A good PCB layout for the TPS62170DSGR involves placing the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
    • Choose X5R or X7R ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. The output capacitor should have a capacitance of at least 10uF and an ESR of less than 100mΩ. The input capacitor should have a capacitance of at least 4.7uF and an ESR of less than 100mΩ.
    • The maximum ambient temperature range for the TPS62170DSGR is -40°C to 125°C. However, the device can operate up to 150°C with derating.
    • The power dissipation of the TPS62170DSGR can be calculated using the formula: Pd = (Vin - Vout) x Iout x η, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and η is the efficiency of the device.
    • The recommended input voltage range for the TPS62170DSGR is 2.7V to 17V. However, the device can operate with input voltages as low as 2.5V and as high as 18V, but with reduced performance.
