Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - LNK6763E LNK6763E

The LNK6763E is an offline switcher from the LinkSwitch-HP family, designed for energy-efficient AC-DC conversion. It operates with a primary-side regulation (PSR) scheme, allowing for high efficiency across a wide load range, with no-load consumption below 30 mW at 230 VAC. The device supports output power levels of up to 21 W with a metal heat sink and 35 W in open frame configurations. This converter features a 650 V MOSFET, which helps to minimize system costs while maintaining performance. It operates at a frequency of approximately 132 kHz, which contributes to reduced transformer size and overall system footprint. The LNK6763E includes extensive protection features such as output short-circuit protection, overload protection, and thermal shutdown, ensuring reliable operation under various conditions. The device is available in multiple package options, including eSIP-7C, eSOP-12B, and eDIP-12B, providing flexibility for different design requirements. Typical applications include LCD monitors, adapters, appliances, and embedded power supplies. The LNK6763E is suitable for engineers looking for a compact, efficient solution for their AC-DC power conversion needs.
