Hello,
I’m planning to use the LT8607 in an always-connected-to-battery design. My main goal is to maintain good efficiency at very light load (~100 µA). From the datasheet, efficiency appears to be around 55% at a 24 V input.
However, I’m seeing a mismatch in simulation. I used the Analog Devices online LT8607 reference design (link below) and only changed the load to 55 kΩ to emulate a weak/light load. In the I_VIN plot I can see the expected burst current behavior, but the quiescent current between bursts is about 1 mA, not ~3 µA as stated in the datasheet.

Could you advise why the simulated IQ is so much higher, and how to configure the model to reflect the datasheet value at light load?
Thanks!
IQ, and burst current (I_vin)
