600 mA. The coupled inductor (transformer) T1 utilized in this board is optimized for small solution size and is not rated for the peak current limit of LM5160. If short circuit protection is required, T1 should be replaced with a coupled inductor (flyback transformer) with primary side saturation current rating greater than the peak current limit of LM5160. -
