Overview
The BD9328EFJ-E2 is a single-output synchronous buck switching voltage regulator manufactured by ROHM Semiconductor. It integrates a power MOSFET and operates within an input voltage range of 4.2 V to 18 V, delivering a maximum output current of 2 A. The adjustable output voltage spans from 900 mV to 12.6 V with a fixed switching frequency of 380 kHz. Designed for surface-mount installation in an HTSOP-J-8 package, it functions reliably across an operating temperature range of -40°C to +85°C while maintaining a typical quiescent supply current of 1.2 mA.
Feature Summary
- Integrates a low on-resistance power MOSFET with the controller in a compact package
- Employs current-mode control architecture for rapid transient response and simplified phase compensation
- Supports operation with low ESR output ceramic capacitors to reduce external component count
Applications
- Industrial equipment power distribution
- Consumer electronics DC-DC conversion
- General-purpose embedded system power supplies
Procurement Notes
Verify the current lifecycle status before procurement, as this component is designated as Not Recommended for New Designs (NRND). Confirm that the HTSOP-J-8 package dimensions align with existing PCB footprints. Ensure compliance with RoHS and REACH SVHC requirements for the specific manufacturing batch. Validate that the 380 kHz switching frequency meets electromagnetic interference constraints for the target application environment.
Selection Notes
Select this regulator when a single output channel is required with up to 2 A load capacity. It is suitable for designs where a fixed switching frequency simplifies filter design compared to variable frequency alternatives. Consider the 4.2 V minimum input voltage constraint against the available supply rails. The integrated MOSFET reduces bill-of-materials complexity but requires adequate thermal management due to the small HTSOP-J-8 footprint.
Part Context
This device belongs to the BD9328EFJ series of integrated MOSFET DC-DC converters. These regulators utilize constant on-time control methods to achieve fast transient responses and low standby power consumption. The series is categorized under PMIC switching voltage regulators, targeting applications requiring efficient step-down conversion with minimal external components.
Replacement Considerations
Consult official substitution lists for direct pin-compatible alternatives. Verify if newer revisions or alternative packages within the same functional family are recommended for new designs given the NRND status.
