Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK632DG-TL LNK632DG-TL

The LNK632DG-TL is a member of the LinkSwitch-II family, designed for energy-efficient constant voltage (CV) and constant current (CC) applications, particularly in adapters and chargers. This device simplifies low power charger designs by eliminating the need for an optocoupler and secondary control circuitry, allowing for clampless designs when used with an external bias circuit. It features a built-in 700 V power MOSFET and employs an ON/OFF control technique for precise output voltage regulation and output current control, making it suitable for battery charging applications. The LNK632DG-TL includes advanced performance features such as cable voltage drop compensation and temperature variation compensation, ensuring reliable operation across varying conditions. Safety is enhanced with auto-restart protection, which significantly reduces power during fault conditions, and hysteretic thermal shutdown that automatically recovers when the temperature falls. The device meets global energy efficiency standards with a no-load consumption of less than 30 mW at 230 VAC input and operates efficiently even at very light loads. The LNK632DG-TL is packaged in a halogen-free and RoHS compliant SO-8C package, making it a suitable choice for environmentally conscious designs. It is ideal for applications including chargers for mobile devices and other portable electronics.
