: This is the switch signal. It must be connected to a 3.3V–5V signal to turn the backlight on.
You would need a heatsink with Θ_sa ≤ 4°C/W (assuming Θ_jc=1.5, Θ_cs=0.5).
The is a universal constant current LED driver board primarily used to upgrade 15-inch to 24-inch LCD monitors from older CCFL (Cold Cathode Fluorescent Lamp) backlighting to modern LED systems . It is often sold as part of a kit that includes the control board and LED strips. Technical Specifications gyd-9e datasheet
: Designed to drive LED light bars in LCD TVs and monitors ranging from 15 to 24 inches. : Features a dual-port design
The GYD-9E acts as a step-up (boost) pulse-width modulation (PWM) converter. It takes a low-voltage DC input and steps it up to the voltage threshold demanded by connected LED backlight strips, ensuring a highly regulated constant current output. Specifications / Values 10V DC to 30V DC (Highly adaptive to fluctuations) Default Output Current ~60mA per channel (Adjustable via onboard resistor pads) Compatible Screen Sizes 15-inch to 24-inch widescreen panels Core Controller IC DF6113 (High-efficiency LED backlight controller) Main Switching Transistor ME15N10 MOSFET (or equivalent high-voltage N-Channel) Output Type Dual-port, constant current feedback loops Board Physical Dimensions 69 mm (Length) × 19 mm / 20 mm (Width) Pinout Configuration and Interface Description : This is the switch signal
Automatically scales dynamically based on the LED load configuration. 10 mA to 1000 mA (Max)
The is a versatile universal LED driver board designed specifically for upgrading, repairing, or replacing backlight systems in LCD monitors and televisions ranging from 15 to 24 inches . This compact converter board allows technicians to replace faulty Cold Cathode Fluorescent Lamp (CCFL) inverters with efficient LED backlighting. GYD-9E Technical Datasheet and Specifications The is a universal constant current LED driver
In summary, the is a highly capable, versatile, and cost-effective solution for anyone looking to repair a modern LCD panel, retrofit an older monitor, or drive a custom LED lighting project.
Like all solid-state relays, the GYD-9E generates heat proportional to the load current. The on-state voltage drop (1.6 V typical) at 9 A results in . Without a heatsink, the internal junction temperature will exceed safe limits within minutes.
