i need 3.3 V for a controller, my only power is solar cell and LiFePo4 battery (4 cells 14.4V), we have long times with controller sleeping.
i make choice with LM5165Y and his high efficiency.
today i am very disappointed, i can't get 3.3V output.
under face the LM5165Y, there is a metallic part, may it has to be grounded ? nothing on the data or on simulator.
Waiting you reply. Our project is stooped. We have to start production quickly, about 1000 to 1500 pcs/month.
