POWER PRODUCTS WIDE-CREEPAGE SWITCHER IC LAUNCHED
Power Integrations has introduced a wide-creepage package option for its InnoSwitch3-AQ flyback switcher IC for automotive applications. A wide drain-to-source- pin creepage distance of 5.1mm eliminates the need for conformal
coating, making the IC compliant to the IEC60664-1 standard in 800 V vehicles while simplifying manufacturing and increasing system reliability. The 1700 V-rated CV/CC InnoSwitch3-AQ
switching power supply ICs incorporate a silicon carbide (SiC) primary switch capable of delivering up to 80 watts of output power. The highly integrated ICs reduce the number of components required to implement a power supply
by as much as 50%, saving space, enhancing system reliability and mitigating component sourcing challenges. An increased drain-pin width is beneficial in withstanding high levels of shock and vibration, especially
in eAxle automotive applications. The new members of the InnoSwitch3-
AQ family will start up with as little as 30 volts on the drain without external circuitry, which is critical for functional safety. Additional protection features include input under-voltage, output over-voltage and over-current limiting.

COMPACT POWER SUPPLY SUITS MEDICAL AND INDUSTRIAL APPLICATIONS
New to Murata Manufacturing Co.’s line of open-frame AC to DC power supplies is the efficient and power-dense PQC600. With its compact size and high-power density, the industrial-grade PQC600 is suitable for the latest medical and industrial applications, such as hospital beds, dentist chairs, medical equipment, and industrial process machinery. This offers 600W of power within a package that is less than 1U in height. Its dependable
performance is guaranteed through certification to the IEC 60601-1 Edition 3 medical safety standard, which includes 2 Means of Patient Protection (MOPP) from primary to secondary, 1 MOPP from the chassis to
ground, and 1 MOPP from output to chassis. Furthermore, the PQC600 complies with the IEC 60601-1-2 4th Edition for EMC standards, ensuring robust electromagnetic
compatibility, and is suitable for use with medical devices that have Type B or Type BF applied parts. With a 600W forced-air cooling design, the power supply achieves an impressive efficiency of 95% at full load. It also has
optimised interleaved Power Factor Correction (PFC) and back-end synchronous rectification, all within a layered design that ensures superior thermal performance. Furthermore, the PQC600 includes a droop current sharing feature, enabling multiple units to be configured in parallel for greater power scalability.

Relec Electronics is proud to announce the latest breakthrough from Advanced Energy. The NCF150 series is a pioneering range of off-the-shelf, convection-cooled, CF-rated AC-DC power supplies which have been designed specifically to meet the rigorous cardiac floating (CF) requirements of the IEC 60601-1 medical safety standard. The NCF150 series from Advanced Energy has been engineered to meet the highest safety standards for medical applications, particularly those in direct contact with the heart, such as dialysis machines and electrosurgery platforms. With its CF rating, the power supplies allow medical OEMs to achieve regulatory compliance with ease and confidence. Key highlights of the NCF150 series include: • High Isolation & Low Leakage: The NCF150 series provides patient leakage current below 10μA, achieving both 2 MOPP isolation and 5 kV defibrillator pulse withstand, a necessity for high-stakes medical environments. • Compact and Powerful: Delivering up to 150 W of output power with voltage options ranging from 12 V to 48 V, these power supplies are engineered to fit into compact spaces while delivering maximum performance. • Universal Input and Efficiency: With a universal input range of 85 to 264 VAC and efficiency rates over 90% at full load, the NCF150 series supports global compatibility and efficient operation in any healthcare setting. • Additional Features: For added versatility, an optional 5 V standby and 12 V fan output are available, providing flexibility for diverse medical equipment needs. These off-the-shelf power supplies eliminate the traditional
need for custom modification. As a result, manufacturers can confidently accelerate product development timelines while meeting CF compliance requirements. The NCF150 series simplifies the process of bringing CF-
compliant products to market, addressing some of the primary challenges in medical device design: • Reduced Component Requirements: The high isolation voltage and low leakage current reduce the need for additional isolation components, simplifying system design.
• Cost and Space Efficiency: By minimising the need for custom-built power solutions, the NCF150 series decreases development costs and the space required within devices.
• Streamlined Development: With its standard design and off- the-shelf availability, the NCF150 allows developers to quickly implement high-performing power supplies, freeing resources to focus on other aspects of product innovation. Applications include cardiac and dialysis machines;
electrosurgical platforms; diagnostic and monitoring devices.
