BM2P181X-Z

Overview

The BM2P181X-Z is a non-isolated PWM DC/DC converter IC designed for AC/DC applications. It integrates a switching MOSFET and features a built-in high-voltage startup circuit rated at 650 V. The device operates with a fixed switching frequency of 65 kHz and supports a maximum duty cycle of 45%. It functions within an input voltage range of 12 V to 26.78 V, drawing an operating supply current of 850 µA. The component is housed in a 7-lead DIP package and is rated for operation between -40°C and +105°C.

Feature Summary

Integrates a high-voltage startup circuit capable of withstanding 650 V.
Provides a simplified design solution for non-isolated high-efficiency converters.
Includes a built-in switching MOSFET to reduce external component count.

Applications

Power systems for products including electrical outlets
Non-isolated AC/DC conversion circuits
High-efficiency converter designs

Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm pinout and electrical characteristics, as variations may exist within the family. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer's datasheet before finalizing procurement. Ensure the ordering information matches the exact required package type and temperature rating.

Selection Notes

Select this component for applications requiring a non-isolated topology with integrated power switching. The 65 kHz switching frequency offers a balance between efficiency and component size. Verify that the input voltage range of 12 V to 26.78 V aligns with the system requirements. Consider the 850 µA supply current for standby power calculations.

Part Context

This part belongs to the BM2P181 series of AC/DC converters manufactured by ROHM Semiconductor. These devices are specifically engineered to simplify the design of power supplies for consumer electronics and appliances that connect to standard electrical outlets. The series emphasizes ease of implementation for non-isolated topologies.
