ROHM Semiconductor BM2P10xJ-Z PWM-Type DC/DC Converter ICs

ROHM Semiconductor BM2P10xJ-Z PWM-Type DC/DC Converter ICs are optimized for isolated AC-DC power supply applications in environments requiring high voltage tolerance and compact design. Featuring an integrated 730V switching MOSFET, these ICs are capable of operating directly from high-voltage AC mains, making them ideal for use in home appliances, industrial control systems, and general-purpose auxiliary power supplies. The ROHM Semiconductor BM2P10xJ-Z series supports efficient power conversion with frequency hopping PWM control to reduce EMI, and includes essential protection features such as overcurrent, overvoltage, overload, and thermal shutdown. With built-in startup circuitry, soft-start functionality, and low standby power consumption, the BM2P10xJ-Z series enables simplified, reliable, and energy-efficient power supply designs in space-constrained applications.
