Part Number: TPS62933O
Other Parts Discussed in Thread: TPS62933EVM

Tool/software:

Hello, 

We will want to implement the "TPS62933ODRLR  SOT583" IC in our product. 

Our specifications include a 24V DC input and a 5V 3A DC output. Kindly provide the schematic and component values according to these requirements.

Thank You.

    Hello, 

    We developed our schematic based on the Typical Application Schematic of the "TPS62933DRLR" IC (refer to attached Image 1 - TPS62933DRLR IC) and the schematic from the "TPS62933EVM-129 3-A Regulator Evaluation Module" (refer to attached Image 2 - TPS62933EVM) for the "TPS62933ODRLR SOT583" IC.

    Please review our schematic (See attached Image3 - TPS62933DORLR) and advise if any updates are needed.
    Thank You.

    Hi Adi

    The circuit looks good to me except that The 6.8uH inductor selection is based on fsw=500kHz when RT is floating(Please see Table 9-1 and Table 10-1 in datasheet).

    You can make R56 NC and keep current inductance, or you can short RT to GND and select a 2.2uH~3.3uH inductor.

    Thanks and best regards.
