BD9326EFJ-LBE2

Overview

The BD9326EFJ-LBE2 is a non-synchronous buck DC/DC converter from ROHM Semiconductor, integrating a low on-resistance power MOSFET. It supports an input voltage range of 4.75V to 18V and delivers up to 3A continuous output current. The device operates at a switching frequency of 380kHz with a minimum output voltage of 0.9V. It features current-mode control for fast transient response and includes protection circuits such as UVLO, thermal shutdown, and overcurrent protection.

Feature Summary

Integrates a low on-resistance power MOSFET within a single chip to reduce external component count and cost.
Utilizes current-mode control architecture to ensure high-speed response characteristics and simplified phase compensation.
Includes comprehensive protection mechanisms including under-voltage lockout, thermal shutdown, and overcurrent protection.

Applications

Industrial equipment requiring wide input voltage ranges
Consumer electronics utilizing standard voltage rails
General-purpose embedded systems

Procurement Notes

Verify the exact suffix against official datasheets, as variations like EFJ and EFJ-E2 exist. Confirm RoHS compliance status and package dimensions (HTSOP-J8) prior to ordering. Ensure design compatibility with the specified operating temperature range and switching frequency requirements.

Selection Notes

Select this component for applications needing a 3A non-synchronous buck solution with integrated power FETs. It is suitable for designs prioritizing simplicity and cost reduction through minimal external components. Verify that the load does not require synchronous rectification for higher efficiency at light loads.

Part Context

This part belongs to the BD9326 series of step-down converters. It shares architectural similarities with other members like the BD9323 and BD9325, differing primarily in output current capabilities and specific feature sets such as synchronous versus non-synchronous topology.
