Industry leading AC/DC converter IC from ROHM

     The BM2SC12xFP2-LBZ is an industry-leading AC/DC converter IC in an all-integrated package that has been built into a compact sticker package (TO263-7L) with a 1700V pressure-resistant SiC mosFETs and control circuits optimized for their drivers. It is mainly applicable to the auxiliary power supply of industrial equipment such as general inverter, AC servo, commercial air conditioner and street lamp which need to deal with high power. In addition, can also ensure long-term stable supply, very suitable for industrial equipment applications.

     The BM2SC12xFP2-LBZ is developed for the application of auxiliary power for various control systems of industrial equipment. In the power conversion circuit of auxiliary power supply, the main switching devices are still common Si (silicon) MOSFET and IGBT, so how to reduce the loss of these power devices has become a big topic in recent years. Design of AC/DC converters with SiC mosFeTs is easier because the BM2SC12xFP2-LBZ has a built-in SiC MosFeTs with excellent energy efficiency. In addition, the series of products are mounted on the table type, support automatic installation, so can reduce the installation cost.

     The BM2SC12xFP2-LBZ significantly reduces the number of external components by incorporating the SiC MosFETs and control ics into a single package. Compared with the ordinary discrete structure with Si MOSFET and 48W output power, it can reduce up to 12 components (AC/DC converter control IC×1, 800V voltage resistant Si-mosFet ×2, Zener diode ×3, resistor ×6) and 1 radiator. In addition, due to the high voltage and excellent noise resistance characteristics of SiC mosFETs, it is possible to use smaller noise and surge resistance components. Not only that, because the control mode adopts the quasi-resonant mode, compared with the PWM mode, it can operate more efficiently with lower noise, so the noise interference (EMI) to other circuits and equipment is very small, and only a few noise reduction measures are needed.

     Integrated packaging can reduce the time of component selection and evaluation work, making design easier. In addition, the built-in SiC MOSFET, with high precision overheating protection, overload protection, power supply voltage pin overvoltage protection, FET overcurrent protection, secondary side voltage overvoltage protection and other protection functions, greatly reduce the number of components, make the product more reliable.
