The GYD-9E is a compact, dual-port constant current LED driver board designed to upgrade 15-inch to 24-inch LCD monitors from CCFL to LED backlighting. Operating on 10V–30V DC, this 69mm x 19mm board features independent port control for stable operation and standard 4-pin input for VCC, ENA, ADJ, and GND signals.

Includes an ON/OFF pin for power management via a 3.3V-5V control signal. Installation and Operating Instructions

This step-down (buck) converter board takes a wide range of input voltages and provides a stable, adjustable constant current to drive one or more strings of LEDs. This is crucial because LEDs are current-driven devices; a constant current source ensures consistent brightness and prevents damage from overcurrent.

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.
