220V to 12V isolated DC-DC converter is a step down converter that uses a synchronous rectification technology, and features high efficiency and power density. It provides that rated output voltage of 12V and the maximum output current of 25A.
Tips: Isolated DC-DC converter working principle
The input circuit rectifies and filters the alternating current into direct current, and controls the energy storage of the primary winding of the transformer through the periodic on-off of the power switch tube, and converts the direct current voltage into a high-frequency square wave voltage, which is boosted or stepped down by the transformer, and then rectified. Filtering becomes DC voltage or current.
