TPS62903-Q1: Schematic review

Part Number: TPS62903-Q1

Hi Team

Please help to review schematic of TPS62903QRYTR1

Spec is 1.Vin = 12V 2.Vo=5V 3.Io=3A

  • Hi Kygo,

    I have the following recommendations for this schematic.

    1) Set R14 to 76.8kΩ, this will select the correct VSET voltage of 5Vout.

    2) Set R13 to 100kΩ to reduce PG resistor losses.

    3) Ensure the 1uH inductor has a high enough current rating. The EVM uses XGL4020-102MEC (30% L drop at 8.8A)

    Thanks,

    Joseph
