BD86123AEFJ-E2

Overview

The BD86123AEFJ-E2 is a synchronous buck DC-DC converter manufactured by ROHM Semiconductor. It operates with an input voltage range of 4.5 V to 18 V and delivers a maximum output current of 3 A. The device integrates a fixed switching frequency of 550 kHz and features a shutdown function for power management. It is housed in an HTSOP-J8 surface-mount package and supports an operating temperature range from -40°C to +85°C. The quiescent supply current is specified at 1.5 mA.

Feature Summary

Integrated synchronous rectification for improved efficiency
Built-in shutdown control capability
Fixed internal switching frequency operation

Applications

Portable electronic devices requiring efficient step-down conversion
Industrial control systems within specified voltage ranges
Communication equipment power supplies

Procurement Notes

Verify component status before integration, as the BD86123AEFJ-E2 is classified as Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that stock may be limited or discontinued. Ensure final design decisions account for potential obsolescence and long-term supply chain stability.

Selection Notes

Select this component only if existing designs require the specific 3 A output and HTSOP-J8 package form factor. Evaluate alternative ROHM parts within the same family for new developments due to the NRND status. Ensure input voltage constraints between 4.5 V and 18 V align with system requirements.

Part Context

This part belongs to the BD86123 series of synchronous buck converters from ROHM Semiconductor. It shares architectural similarities with other members like the BD86120EFJ-E2 but differs in output current capacity. The series targets compact power management solutions for portable and industrial applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, consult ROHM Semiconductor directly for recommended alternatives or updated product line information.
