BD86120EFJ-E2

Overview

The BD86120EFJ-E2 is a synchronous buck converter manufactured by ROHM Semiconductor, designed for efficient DC-DC step-down applications. It operates within an input voltage range of 4.5 V to 18 V and delivers a maximum output current of 5 A. The device supports adjustable output voltages from 306 mV to 14.4 V with a fixed switching frequency of 550 kHz. It features a low quiescent supply current of 1.5 mA and functions reliably across an extended temperature range of -40°C to +85°C. Packaged in an HTSOP-J-8 surface-mount format, this single-output regulator integrates internal power MOSFETs for compact system design.

Feature Summary

Integrates high-side and low-side power MOSFETs for synchronous rectification
Utilizes constant on-time control architecture for fast transient response
Includes shutdown function to minimize standby power consumption

Applications

Portable electronic devices requiring efficient power management
Industrial equipment with moderate current demands
Consumer electronics utilizing single-rail power distribution

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package and tape/reel specifications. Check current lifecycle status as the part may be subject to obsolescence notices. Ensure compliance with RoHS directives and relevant environmental standards before integration into final products.

Selection Notes

Evaluate the 5 A output capability against peak load requirements to ensure adequate thermal headroom. Consider the 550 kHz switching frequency for inductor size trade-offs versus electromagnetic interference. Verify that the 4.5 V minimum input voltage aligns with the source supply characteristics under all operating conditions.

Part Context

This component belongs to ROHM's series of integrated MOSFET DC-DC step-down converters. These regulators are engineered for applications demanding high efficiency and rapid transient response. The family utilizes constant on-time control methods to maintain stability at light loads while supporting low-inductance designs.
