The LNK3771D-H003-TL from Power Integrations is an Off-line CV Flyback Switch IC that is ideal for single and multi-output power supplies in appliances, home and business automation, and industrial system applications. It requires an input voltage of 85 - 265 V.  It is designed for non-isolated configurations with a high-current, 5 V output, ensuring optimal performance. This PMIC maintains high efficiency even at low loads, with over 85% efficiency at a 100 mW load. This PMIC is a high-efficiency solution, consuming less than 5 mW under no-load conditions while also eliminating the need for bias winding and associated circuitry by optimally using the DRAIN and VOUT pins. It not only conserves energy with its low power consumption but also simplifies designs by efficiently utilizing the DRAIN and VOUT pins for startup and operation. This PMIC is available in a surface-mount package that measures 9.91 x 6.07 x 1.69 mm.
