Power Integrations, Inc. LED Drivers LNK413EG

The LNK413EG is part of the LinkSwitch-PH family of LED driver ICs designed for off-line applications. It features a single-stage power factor correction (PFC) and constant current control, which simplifies the design of LED drivers while enhancing efficiency, achieving over 90% in many cases. This device operates within a universal input voltage range of 85 to 265 VAC and is optimized for non-dimming applications, providing a maximum output power of 12 W. The LNK413EG integrates a high-voltage power FET and a PWM controller, eliminating the need for external components such as optocouplers and current sense resistors, which reduces the overall component count and complexity. It includes advanced protection features such as auto-restart for short-circuit protection, open circuit fault detection, and thermal shutdown with hysteresis. This IC is packaged in an eSIP-7F format, which is halogen-free and RoHS compliant, making it suitable for environmentally conscious designs. The LNK413EG is particularly well-suited for applications requiring reliable performance and long operational life, as it does not utilize electrolytic capacitors.
