POWER INTEGRATIONS LNK3307D-TL Datasheet & Stock

LinkSwitch-TNZ, a new switching power supply IC family that reduces standby consumption by up to 60% in smart home applications and white goods. Combines offline power conversion, lossless zero-cross detection and optional X-capacitor discharge functions in a compact SO-8C package. Typical discrete AC zero-cross detection circuits require many components and can consume up to half of the standby power budget in typical applications. With integrated lossless AC zero-cross detection, IC provides best-in-class light load efficiencies, enabling more system features to be powered in standby while still meeting stringent standby regulations. LinkSwitch-TNZ switching power supply ICs enable ±3% regulation across line and load, no-load consumption of less than 30mW with external bias and have an IC standby current of less than 100µA. Applications include smart home and building automation, IoT, HBA, industrial controls, dimmers, switches and sensors with and without neutral wire, white goods.
