LM5069: Suggest MOSFET and clamping diode for design...

Part Number: LM5069
Other Parts Discussed in Thread: TPS1663

Dear Sirs,

Below is my customer design requirement, please help to suggest the suitable MOSFET and diode for design.

normal input voltage: 12V~28V

clamping voltage for 28V: 35.5V

output current: 4A

UVLO: 9.6V~10.2V

OVLO: 32V~35V

The calculator file also as attached, please help to review if there is any problem!

Thanks.

  • Hi Peter,

    Please use TPS1663x device.

    Advantages are 

    • Accurate over current protection ± 7%  Vs ± 11.8% for LM5069
    • Built in over temperature protection for the internal FET in TPS1663  
    • UL certification
    • Integration saves board space
