LM76003: review attached schematics

Part Number: LM76003

Hi Team,

Please review the review attached schematics section LM76003RNPR input is 17V to 42V DC and Output 5V at 3.03A design.



  • hi, Yaseen,

    The schematic looks pretty good. I have checked the pins connection: 

    • EN is tied high or connected to on/off control. yes it has.
    • SS/TRK: this pin can be left floating for 6.3ms timing or place external capacitor. i see you reserve the place. 
    •  RT pin has a resistor to ground to set the frequency. yes it has.
    •  SYNC/MODE pin to ground for PFM and tie to high signal for FPWM. the mode is right to set.
    • PG connect to Vout for 5V ,it is good.
    • Inductor choose 10uh 6A works good for 5V 3A output.

    Suggestion is,  to leave space for CFF next to R770 if loop debug need, and add some place for electrical capacitor too.
