This HPD004B series LED driver circuit is designed for driving high power LEDs. The LED used will have a voltage drop which is specified at the intended operating current. The resistor value is computed by subtracting the LED voltage drop from the supply voltage, and then dividing by the desired LED operating current.
The series is constant current driver which provides high power LED with constant current while operating. The table below provides more detail information for this series. Please feel free and contact us for more or inquire the product today!
