SSL5018TE/1Y Applications Field and Working Principle
SSL5018TE/1Y is a constant-current LED drive chipset developed by the chip company Shunlong Technology, aimed at the constant current drive of high-brightness LEDs. It can monitor the brightness of LED and the temperature of LED driving head, has multiple dimming modes and a variety of communication interface methods.
Applications Field
- Indoor display devices
- Outdoor signage displays
- Vehicle displays
- Signage lighting
- General lighting
Working Principle
SSL5018TE/1Y is a regulator that sets the maximum current output of a device by controlling the average current of a load by pulse width modulation (PWM). SSL5018TE/1Y is a member of class-D amplifier. Class-D amplifiers are known as switching amplifiers. As the name implies, the output transistor changes between two states: on and off. When the output transistor is on, the current will flow in the load, and when it is off, the current stops flowing. The average load current is determined by the on/off ratio of the transistor, and the switching frequency is determined by the time it takes to turn on and off. By controlling the on/off ratio at different frequencies, the average current in the load loop can be adjusted very accurately.
In comparison to a traditional regulator, the class-D amplifier has much higher efficiency and much lower heat dissipation. Higher current accuracy is also achieved by using more precise voltage and current sources.
Power Management Features
- Constant-Current Control: SSL5018TE/1Y can accurately control the output current to guarantee system stability and protect the operational performance of other components.
- Wide- Range Dimming: SSL5018TE/1Y can easily provide a wide range of dimming ratios to ensure precise control for various applications.
- Extensive Protection Features: SSL5018TE/1Y is equipped with various protection features, including short-circuit protection, over- voltage protection, over-current protection and thermal protection.
Conclusion
SSL5018TE/1Y is a high performance constant-current led driver developed by Shunlong Technology. It can be used in a variety of applications such as indoor displays, outdoor signage displays, vehicle displays, signage lighting, and general lighting. It has a wide range of dimming ratios, precise control and various protection features, guaranteeing system stability and protecting the operational performance of other components.
