We've got a 3V6 (battery) to 14V boost circuit using a LT3489.
It works fine except the idle current consumed by the circuit with no load is high @ 15mA.
We've pretty much followed the data sheet in terms of both the schematic and the PCB layout.
15mA seems quite a high idle current.Can anyone point us in the right direction with this?
Data sheet:
Our schematic:
Thanks.
