Power Integrations RDK-1053 60W Dual-Output Flyback Power Supply

Power Integrations RDK-1053 60W Dual-Output Flyback Power Supply utilizes the advanced InnoMux™ IMX2353F mixed-signal IC and PowiGaN™ technology for superior efficiency and performance. This design delivers two isolated, regulated outputs (5V at 2.5A and 24V at 2A) from a single power stage, making it ideal for applications requiring multiple voltage rails. Operating over a wide universal input range of 70VDC to 1000VDC, the Power Integrations RDK-1053 achieves greater than 90% efficiency, reducing heat and improving reliability.

The integration of primary-side regulation, synchronous rectification, and multi-output control within the InnoMux IC minimizes component count and board size, enabling compact and cost-effective designs. Additionally, the use of PowiGaN™ technology supports high-voltage operation up to 1700V, enhancing robustness for demanding environments. Built-in protection features, including overvoltage, overcurrent, and thermal safeguards, ensure safe and reliable operation. This solution is optimized for industrial, consumer, and networking applications where high efficiency, space savings, and multiple regulated outputs are essential.
