Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK4013D-TL LNK4013D-TL

The LNK4013D-TL is a member of the LinkSwitch-4 family of integrated circuits designed for energy-efficient, primary-side regulated constant voltage/constant current (CV/CC) applications. This device simplifies the design of low-power adapters and chargers by eliminating the need for an optocoupler and secondary control circuitry, which reduces component count and complexity. It operates within an input voltage range of 85 to 265 VAC and can deliver a maximum output power of 10 W. The device features dynamic base drive technology that optimizes the switching characteristics of the BJT transistor, enhancing efficiency and performance. It also includes advanced protection features such as overvoltage and short-circuit protection, as well as over-temperature protection. The LNK4013D-TL is designed to meet energy efficiency standards, achieving a no-load consumption of less than 30 mW at 230 VAC input. It operates at a switching frequency of up to 65 kHz, allowing for smaller transformer sizes. The device is packaged in a halogen-free and RoHS compliant format, making it suitable for environmentally conscious designs. This product is ideal for applications such as chargers for portable devices, adapters, and networking equipment, making it a versatile choice for engineers looking to implement efficient power management solutions.
