LED drivers are electronic devices which regulate LED’s current. LED lamps and LED luminaires often require a LED driver to ensure consistent operation and to protect the LED’s from damage. LED drivers provide a wide range of options and efficiency works which match different LED applications. As they regulate the LED’s current, the power output can be adjusted from 20 mA up to 1 A. The LDH-45B-500DA LED driver is specifically designed for LED lighting applications where high efficiency, high precision, and low EMI are required.

The LDH-45B-500DA LED driver is a buck LED driver that provides an output current of 500 mA. It features a reliable 45 V wide input voltage range and high switching frequency of up to 1.5 MHz. The driver also features a high efficiency up to 88%, low EM and low ripple noise, making it ideal for LED lighting applications.

The LDH-45B-500DA LED driver works by controlling a switch which continuously adjusts the internal current in order to maintain the desired output current. When the output current begins rising, the switch is turned off, the current is shut off, and the output voltage decreases. At the same time, the voltage between the two terminals begins to increase, driving the current into the load and thus maintaining a constant output current.

The LDH-45B-500DA LED driver is suitable for a wide range of lighting applications such as in-car illumination systems, automotive interior lighting, smart home products, panel mount luminaires, and spotlights. The driver is also compatible with various dimming systems including 1 ~ 10 V, PWM and DALI.

The LDH-45B-500DA LED driver features a built-in circuit that provides enhanced thermal protection and requires no external components. It also features over temperature protection and overload protection, which protects LEDs and their components from damage due to overloading. This LED driver also provides a high power factor and low total harmonic distortion (THD).

In summary, the LDH-45B-500DA LED driver is ideal for LED lighting applications due to its high efficiency, high precision, low EMI, wide input voltage range, and high switching frequency. It is suitable for a wide range of lighting applications, as well as various dimming systems. Furthermore, it features built-in circuit protection, high power factor and low THD.
