Product Introduction
The LCD flyback transformer is a core magnetic component in low-power isolated power supplies for LCD driving. It is essentially a coupled inductor with an air gap, combining the functions of voltage conversion, electrical isolation, and energy storage. Its power rating is typically ≤50W, and it is widely used in LCD backlight boards, adapters, and auxiliary power supplies. Common core configurations include EE type, EC type, and EDR type.
Product Features
The commonly used core materials for LCD flyback transformer products are manganese-zinc PC40 and PC44.
To prevent DC bias saturation, enhance energy storage, and reduce effective permeability, the core typically employs a center-gap structure with an air gap in the center leg.
The product features a relatively simple structure, low cost, easy implementation of multiple DC output voltages, compact size, and high operating efficiency. It supports fully automated production with good consistency, making it the best choice for cost-effective transformer solutions.
Application Fields
LCD flyback transformers are mainly applied to:
FAQ
Q: What are the functions of varnish impregnation and baking process for conventional transformers?
A: Mechanically secure the winding and magnetic core to prevent audible noise and vibration induced by alternating current flow.
Impregnate or fill the interstices within the winding assembly to enhance dielectric strength and provide protection against moisture ingress.
Enhance thermal dissipation capability to minimize steady-state temperature rise under continuous long-term operation.
