Reference Design

A system-level evaluation board that combines ROHM's IC and discrete products. We have already solved not only the characteristics of individual products but also the problems that may occur when combining them to build a system, thus contributing significantly to the reduction of development time for our customers.

Non-Isolated PWM type Buck Convertor 8W 20V Output

Summary

non-isolated from inputs from 90 Vac to 264 Vac, with an output maximum current of 0.4A It was developed mainlu for power supplie for IH cookers and IH cookers. The non-insulated output can be used as a power supply for control of inverters,etc. A PWM controller for AC/DC power supplies,the BM2PAB1Y provides the ideal system for small appliances with outlets.
