EE10 Vertical High Frequency Transformer LED Mini Flyback Transformer High Voltage
EE10 Vertical High Frequency Transformer LED Mini Flyback Transformer High Voltage
1.Product Description
This is an EE10 model vertical high-frequency transformer designed specifically for LED drivers and micro switching power supplies; It adopts a flyback circuit topology, which can work efficiently at high frequencies, and achieves voltage conversion through electromagnetic induction principle, thereby increasing the low input voltage to the high output voltage required to drive LED chips. Its compact vertical structure particularly saves circuit board space and is a key component for achieving high-voltage power supply and safe isolation in miniaturized and high-efficiency electronic devices.
Core feature analysis:
-EE10: Refers to the specifications and dimensions of the magnetic core, which is very compact and suitable for miniaturization design.
-Vertical: refers to the transformer coil being wound on the magnetic core and standing vertically on the circuit board, which is opposite to "horizontal" and can effectively reduce the board area.
-High Frequency: Designed specifically for switching frequencies ranging from tens of KHz to hundreds of KHz, this is the key to improving efficiency and reducing size in modern switching power supplies.
-Mini Flyback Transformer: specifies its working principle (flyback type) and physical characteristics of miniaturization. The flyback topology structure is simple and very suitable for low-power isolated power supplies.
-High Voltage: Its main function is to generate a sufficiently high voltage to drive multiple LED chips connected in series.
-LED: Clarified its main application area, which is used in the driving power module of LED lighting products.
