LMR36006-Q1: How much output voltage could he regulate?

Part Number: LMR36006-Q1

Hi team, 

Could you tell me how much output voltage capability LMR36006AQRNXRQ1 has?

I found that Vout (Min) (V) is 1V and Vout (Max) (V) is 57V respectively on product folder page; https://www.ti.com/product/LMR36006-Q1
However, I wonder if it is correct because I could not find this spec in datasheet.

Regards,
Ochi 

  • Hi Ochi,

    The max output voltage can be estimated by below:

    • Vo-max=Dmax*Vin--Io*(Rdcr+Rdson_HS)
    • assume Toff_max=100ns at 60Vin, so Dmax=0.986
    • Rdcr is inductor DCR
    • Rdson_HS is 435mohm.

    Max 57V output is estimated by equivalent Dmax=95% which can cover most application conditions.
