Block Diagram

The block diagram illustrates the internal components and signal flow of the ELG-300 LED driver, including EMI filter, rectifiers, PFC circuit, power switching, and control circuits.

Key Signals: PFC fosc: 45KHz, PWM fosc: 100KHz

Driving Methods of LED Module

This series can operate in either Constant Current mode (direct drive) or Constant Voltage mode (typically with an additional DC/DC driver) to drive LEDs.

The graph shows the relationship between output voltage (Vo), output current (Io), and protection modes (Constant Voltage area, Constant Current area, Hiccup Protection). In the constant current region, the output voltage depends on the end system's configuration. For compatibility issues, contact MEAN WELL.
