I have found several circuits using a LM317 with pass transistor to up the current capability, but they all seem a bit like an overkill for my purpose.
I have a Turnighy Accucel 6 LiPo battery charger. It requires 12-18V 5A input to it.
I have a 18.5V 6A laptop PSU
I would like to drop the voltage to suit the charger.
Note: The charger cuts out on over-voltage, actually even when close to 18V, so ideally I am aiming for 15V. I will mostly use for charging 3S LiPos, so 15V means it will not need step up.
I have a 3-15V brick PSU 4A, but ideally I would like to use the dedicated 18.5V for the LiPo charger.
