Power Integrations Announces New Multi-Output Zero-Voltage Switching Flyback Converter ICs
Power Integrations Introduces IMX2353F: A Highly Integrated ZVS Flyback Switcher IC for Multi-Output Power Supplies
Power Integrations has launched the IMX2353F, a new addition to the InnoMux2-EP family of highly integrated Off-Line Zero Voltage Switching (ZVS) Flyback Switcher ICs. This IC is specifically designed for multi-output power supply applications and features a 1700 V GaN (Gallium Nitride) switch, enabling efficient operation with a nominal input voltage of up to 1000 VDC. Its advanced feature set and robust design make it ideal for powering a variety of devices with high efficiency and low power dissipation.
Key Features of the IMX2353F:
- Multi-Output Support: The IMX2353F supports up to three independently regulated outputs using a single transformer and controller, eliminating the need for bulky and costly post regulators and simplifying power supply design.
- High-Voltage Operation: Featuring a robust 1700 V GaN power switch, the IC is capable of handling high input voltages up to 1000VDC, enabling high-efficiency designs for various applications.
- Advanced Flyback Controller: The integrated multi-mode quasi-resonant DCM (Discontinuous Conduction Mode) and CCM (Continuous Conduction Mode) flyback controller with synchronous rectification ensures optimal performance across a wide range of load conditions.
- FluxLink Feedback: The integrated FluxLink feedback technology eliminates the need for optocouplers, further simplifying the design, improving efficiency, and enhancing system reliability.
- Zero Voltage Switching (ZVS): The IC utilizes Zero Voltage Switching (ZVS) in DCM-only mode, minimizing switching losses and significantly improving efficiency, especially at light loads. This is achieved through advanced SR FET control.
Performance Highlights of the IMX2353F:
- High Efficiency: Utilizing PowiGaN technology, the IMX2353F enables power supply efficiencies exceeding 90%, minimizing energy waste and reducing operating costs.
- Excellent Transient Response: The IC offers excellent load regulation with less than ±5% constant voltage (CV) deviation during a 100% load step, ensuring stable output voltage under dynamic load conditions.
- High Output Capability: Provides up to 200 V output for both CV and constant current (CC) configurations, making it suitable for a wide range of applications, including LED drivers and industrial power supplies.
Comprehensive Protection and Safety Features:
- Advanced Protections: The IMX2353F incorporates a suite of advanced protection features, including overload protection for each output, primary sensed output overvoltage protection (OVP), and open SR-FET gate detection, ensuring robust system protection.
- Thermal Management: Hysteretic thermal shutdown protects the IC from damage in case of excessive temperature rise.
- Input Monitoring: Integrated brown-in/brown-out detection and overvoltage protection enhance input safety and prevent malfunction under abnormal input conditions.
- LED Safety Features: Includes specific protection features against LED short and open circuit conditions, making it ideal for LED lighting applications.
- Regulatory Compliance: Provides reinforced isolation with over 4000 VAC isolation voltage, meeting stringent safety standards such as UL1577 and TUV (EN62368). It is also fully compliant with the EN61000-4 suite of standards for electromagnetic compatibility (EMC).
Target Applications of the IMX2353F:
- High-efficiency drivers for monitors and TVs
- Power supplies compliant with energy efficiency standards such as Energy Star 8, CEC, and 2021/2023 EU labeling requirements
- Industrial systems
- Smart meters and appliance applications
The IMX2353F is available in a compact InSOP-T28G package, designed for efficient heat dissipation without the need for additional heat sinks, simplifying PCB design and reducing system cost.
