CA-901 LCD TV switching power supply module — 12V/24V output, flyback SMPS, universal replacement
The CA-901 is a compact, high-performance LCD TV switching power supply (SMPS) module designed as a universal replacement for faulty or failed power supply boards in LCD televisions up to 46 inches. Built around a flyback topology with TL431-based DC voltage feedback, it delivers stable, well-regulated 12V or 24V output — selectable via a simple pad connection — making it adaptable to a wide range of LCD TV power requirements.
Its small form factor, wide input voltage range, and plug-and-play design make it ideal for fast LCD TV repair and maintenance, eliminating the need to source expensive OEM replacement boards. Engineers and repair technicians can use it as a drop-in replacement or as a standalone regulated power module in custom electronics projects.
