The IMX2353F from Power Integrations is an Off-Line Zero Voltage Switching (ZVS) Flyback-Based Load Switch designed for multi-output applications. This switch requires an input voltage of 200-1000 V. It delivers a continuous output power of 70 W. It supports up to three independently regulated outputs using a single controller and transformer, eliminating the need for post regulators. This switch incorporates a multi-mode flyback controller capable of quasi-resonant Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM). It delivers excellent transient response (<±5% CV for 100% load step) and outputs up to 200 V for constant voltage (CV) and constant current (CC) configurations. 

This switch includes safety features such as primary sensed output overvoltage protection (OVP), open SR-FET gate detection, hysteretic thermal shutdown, and input voltage monitoring for brown-in/brown-out and overvoltage protection. It has a reinforced isolation of >4000 VAC and is full compliant with regulatory standards such as UL1577 and EN62368. This RoHS-compliant power switch IC is available as a surface-mount package that measures 9.40 x 13.43 x 2.26 mm and is ideal for industrial, smart meter, appliance, and high-performance drivers for monitors and TV applications.
