BM2P161W-Z

Overview

The BM2P161W-Z is a PWM DC/DC converter IC with an integrated switching MOSFET for non-isolated applications. It operates within an input voltage range of 8 V to 18.16 V and features a fixed switching frequency of 65 kHz. The device utilizes current mode control for superior transient response and includes a built-in 650 V start circuit. It supports light load modes with frequency reduction and hopping functions to enhance efficiency and reduce EMI. The component is housed in a DIP-7 package, rated for operation between -40°C and +105°C, and offers per-cycle overcurrent protection.

Feature Summary

Integrates a 650 V super junction MOSFET and start circuit for simplified design
Employs current mode control with per-cycle current limiting for stable performance
Includes frequency hopping and burst operation at light loads to minimize EMI and power consumption

Applications

Non-isolated AC/DC converters for products with power sockets
Low power consumption adapter designs
Compact power supply systems requiring high efficiency

Procurement Notes

Verify the specific suffix and packaging configuration against official ROHM documentation before ordering. Confirm that the application environment remains within the specified temperature range and does not involve automotive equipment, as this standard-grade product is explicitly not recommended for such use cases.

Selection Notes

Select this component for non-isolated buck converter designs requiring integrated high-voltage MOSFETs. It is suitable for applications needing fixed 65 kHz switching frequencies with enhanced EMI mitigation features. Ensure the input voltage stays within the 8 V to 18.16 V window and consider the DIP-7 package constraints for thermal management.

Part Context

This part belongs to the BM2P161 series of AC/DC converters from ROHM Semiconductor. These ICs are designed to provide efficient power conversion for various consumer electronics. The series emphasizes low standby power and compact design through integrated components, targeting markets where space and energy efficiency are critical constraints.
