However, as high heat/high loss DMOSFETs and planar MOSFETs are still widely used in AC/DC converter ICs, until now it has been difficult to provide tens of watts of output power in a surface mount package. To solve these issues, ROHM developed new compact surface mount high power 45W models BM2P06xMF-Z. They are equipped with an original low-loss SJ (Super Junction) MOSFET together with optimized PWM control circuitry – facilitating the development of 85V to 264V AC/DC converters. Adopting a surface mount package supports automatic board mounting (which was previously difficult to do in the past). Meanwhile, the implemented functions ensure compliance with the IEC62368 safety standard, even when the discharge resistor (a source of loss during standby) is removed. Additionally, original low standby power control technology is applied – resulting in extremely low standby power consumption. Supply voltages up to 60V (VCC) are also supported – eliminating the need for an external step-down power supply circuit. Compared to general products with equivalent performance, automatic mounting contributes to lower factory mounting costs. Moreover, ROHM is able to reduce standby power by over 90% along with the number of power supply circuit components by four, contributing to greater power savings and higher reliability in applications. Going forward, ROHM will continue to deliver greater system energy savings and optimization by not only developing a wide range of power semiconductors and advanced analog ICs, but also by providing optimal solutions for each application. Application Examples Consumer electronics such as air conditioners, appliances, monitors, and hair dryers Industrial equipment including inverters, AC servos, routers, and office automation devices Suitable for AC/DC converters up to 45W output in consumer and industrial applications New Product Related AC/DC Converter IC Lineup Availability: Now (samples), January 2022 (mass production) Both the new product and an evaluation board are

THM 60WI Series Delivers high power for your medical applications (60 Watt DC/ DC converter) Wide 4:1 input voltage 60 W DC/DC converter in a compact 2.3 x 1.45 ” plastic case I/O isolation 5000 VAC rated for 250 VAC working voltage Certification according to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP Risk management process according to ISO 14971 Acceptance criteria for electronic assemblies acc. to IPC-A-610 Level 3 Low leakage current <4.5 μA Operating temperature –40°C to 75°C EMC compliance to IEC 60601-1-2 4th edition Operating up to 5000m altitude 5-year product warranty The THM 60WI series is a range of medical 60 Watt DC/DC converters in a compact 2.3” x 1.45” plastic package and with wide 4:1 input voltage range. They provide a reinforced isolation system (5000 VAC) and a very low leakage current of less than 4.5 μA. With a high efficiency of up to 92% and highest-grade components the converters can reliably operate in an ambient temperature range of –40°C up to +75°C with derating. For more demanding applications regarding temperature, Traco also offers a special heatsink which will greatly increase the thermal capabilities for natural convection conditions. The units are approved according to IEC/EN/ES 60601-1 3rd edition for 2 x MOPP as well as IEC/EN/
