The LNK405EG is a great device for porting power from one circuit to another. Incorporating the latest technology, this PMIC - LED Drivers is capable of delivering low power with high efficiency. It is designed to provide high-performance LED illumination solutions for a wide range of LCD and LED applications.

The LNK405EG is a cost-effective low power LED driver, designed to increase the efficiency of light-emitting diode (LED) systems. The driver offers up to 12A of user selectable direct current (DC) current feeding capability. It also offers a wide range of adjustable frequency, voltage and output current options, allowing designers to configure the LED system to maximizing efficiency and minimize power consumption. The device offers an adjustable current slew rate control to minimize inrush current and reduce stress during hot or cold periods.

The internal architecture of the LNK405EG consists of two power supply concept, the primary and the secondary. The primary power supply input and output are completely isolated from each other, thus reducing additional EMI issues. The primary power supply is compatible with a wide range of input voltages, including 12V, 24V, 48V and 200V. The output current can be adjusted via manual and optional external dimmers and digital potentiometers.

The secondary power supply consists of a series of transistors, which are connected to the primary through a Zener diode. This configuration provides a better voltage control and increase efficiency at the switching frequencies. The intelligent PWM control of the device allows it to automatically adjust the frequency, pulse width, and current according to the load. The device can achieve a maximum power efficiency of 85%, reducing losses and extending the life of the system.

The LNK405EG also utilizes current sensing to detect any potential overload and automatically shut down the device to prevent damage. The device offers a flexible temperature compensation circuit for for better efficiency, protection and reliability in any temperature environment. This driver also offers a low EMI version that reduces the radiation of conducted noise and improves the immunity of the device to radiated interference.

For those that need high performance and variable current, the LNK405EG is the perfect PMIC - LED Drivers. Its excellent performance and design make it an ideal choice for a wide range of applications, including LCD and lighting systems. It is an efficient, cost-effective solution for both new and existing applications.
