The LNK406LG is a highly advanced Power Management Integrated Circuit (PMIC) specifically designed for LED Drivers. It is a low-voltage monolithic IC, offering high efficiency, very low standby power losses and significant space savings over traditional power solutions. The LNK406LG is ideal for enabling very efficient LED lighting systems, and is suitable for both indoor and outdoor applications.

The LNK406LG has an internal oscillator with an adjustable output frequency of up to 500kHz, enabling optimized switching losses and low audible noise. This makes it possible to achieve extremely high conversion efficiency of up to 96% for an output power range from 4W to 25W. This is especially useful for lighting applications where LEDs may be connected to the same output, since efficiency depends on all LEDs having the same forward voltage.

The LNK406LG also has a very comprehensive set of built-in protections and fault conditions, which offer maximum safety to the system. In particular, it has overvoltage, over-temperature and current limit protections, as well as hiccup auto-restart after a given fault condition. These safety features ensure reliable and secure operation.

The LNK406LG can be configured in either buck or boost mode and has a wide input voltage range from 5V to 60V, making it suitable for both AC and DC inputs. It also supports up to two channels that can be used to drive two different LED strings. This makes the LNK406LG an ideal choice for designs such as LED wall washers and floodlights.

The LNK406LG is easy to use, with minimal external components required. The LED driver can be easily programmed with digital logic or PWM, and is configurable for either buck or boost operation. The device is also adjustable for pulse-by-pulse current limit, allowing for safe operation and compensation for LED lamp variations. The output can be configured to run in either constant current mode or constant voltage mode, depending on the application.

This highly efficient and versatile LED driver is suitable for a wide range of home and commercial lighting applications, such as down lights, wall washers, flood lights, signage and stage lighting. With its ease of use and comprehensive set of protection features, the LNK406LG is the perfect choice for designers seeking to make the most of their LED lighting designs.
