Reviewing the LV2862 datasheet, I see efficiency curves for operation at Vin = 12, 16, 18V, Vout = 3.3, 5, 12V.
Please provide efficiency curve for Vout=3.3V for Vin=24V and 36V, for Iout=1 to 10 mA.
Are there any limitations that would prevent the device from operating with Vout=3.3V and Vin=60V?
Thanks, Bryan Zublin
