Power Integrations, Inc. PMIC - PMIC - AC DC Converters, Offline Switchers - TOP223GN-TL TOP223GN-TL

The TOP223GN-TL is a member of the TOPSwitch-II family of offline PWM switches designed for AC to DC conversion. It operates efficiently with a maximum output power of 15W for 100/115/230 VAC input and up to 30W for a wide input range of 85-265 VAC. The device features a three-terminal configuration that integrates a power MOSFET, PWM controller, high-voltage startup circuit, and fault protection circuitry, which simplifies design and reduces component count. This converter supports multiple topologies including Flyback, Forward, Boost, and Buck, making it versatile for various applications such as TVs, monitors, and audio amplifiers. It achieves high efficiency of up to 90%, minimizing AC/DC losses. The built-in auto-restart and current limiting features enhance reliability, while the latching thermal shutdown provides additional system-level protection. The device is available in a TO-220 package, which aids in thermal management by allowing direct heat transfer to the PCB, potentially eliminating the need for external heat sinks. Engineers considering the TOP223GN-TL for their projects will benefit from its cost-effectiveness, ease of use, and robust performance in a compact design.
