BM2P016-Z

Overview

The BM2P016-Z is a PWM type DC/DC converter IC manufactured by ROHM Semiconductor, designed for AC/DC conversion applications. It integrates a switching MOSFET and operates in a Buck topology with one output channel. The device supports an input voltage range of 8.9 V to 26 V and delivers an output current of 10.4 A. Key electrical parameters include a switching frequency of 70 kHz, a maximum duty cycle of 82%, and a quiescent operating current of 1.2 mA. It functions within a temperature range of -40°C to +105°C and utilizes a DIP-7 through-hole package.

Feature Summary

• Integrates a switching MOSFET and control circuitry into a single component for simplified design.
• Employs PWM current mode control to achieve excellent bandwidth and transient response performance.
• Includes built-in protection mechanisms such as thermal shutdown, under-voltage lockout, and per-cycle over-current limiting.

Applications

• Power supply systems for consumer electronics requiring non-isolated or isolated topologies
• Adapters and chargers for general-purpose electronic devices
• Low-power AC/DC conversion circuits in home appliances

Procurement Notes

Verify the specific suffix and revision level against the official ROHM datasheet to ensure compatibility with your design requirements. Confirm that the DIP-7 through-hole package aligns with your PCB footprint and assembly process. Check for any RoHS compliance documentation if required by your manufacturing standards. Ensure the input voltage range matches your system's power source specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution integrating both control logic and power switching is required. It is suitable for designs needing fixed-frequency operation at 70 kHz with integrated current sensing capabilities. Consider its thermal performance and operating temperature range relative to your enclosure constraints. Evaluate whether the 10.4 A output current capability meets your load requirements without excessive derating.

Part Context

This part belongs to ROHM's series of AC/DC converter ICs designed for high efficiency and miniaturization. These controllers typically integrate high-voltage MOSFETs and startup circuits to reduce external component count. The BM2P016-Z specifically targets applications where space savings and simplified bill of materials are prioritized while maintaining reliable power conversion performance.

Replacement Considerations

Consult ROHM's official cross-reference guides for verified substitutes. Ensure any replacement maintains compatible pin configurations, voltage ratings, and thermal characteristics. Verify that alternative parts support the same DIP-7 package if board layout changes are not permitted.
