Overview
The BD95835EFJ-E2 is a synchronous buck converter manufactured by ROHM Semiconductor, designed for single-output voltage regulation. It operates within an input voltage range of 4.5 V to 18 V and delivers up to 3 A of output current. The adjustable output voltage spans from 900 mV to 10.8 V. The device utilizes a fixed switching frequency of 800 kHz and functions reliably across an operating temperature range of -40°C to +85°C. Packaged in an HTSOP-8 format, it integrates shutdown capabilities for power management efficiency.
Feature Summary
- Integrates synchronous rectification for improved conversion efficiency
- Employs constant on-time control architecture for rapid transient response
- Features low quiescent current operation to minimize standby power consumption
Applications
- Portable electronic devices requiring efficient step-down regulation
- Industrial equipment power distribution systems
- Communication infrastructure power supplies
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix designation matches project requirements. Check current lifecycle status as components may be subject to discontinuation notices. Ensure compliance with relevant environmental regulations before integration into final assemblies.
Selection Notes
Evaluate thermal performance constraints based on the HTSOP-8 package limitations. Assess input voltage stability against the specified 4.5 V to 18 V operational window. Consider the 800 kHz switching frequency regarding electromagnetic interference and external component selection. Verify that the 3 A current capability aligns with peak load demands.
Part Context
This component belongs to the BD95835EFJ series of integrated MOSFET DC-DC buck converters. These devices are engineered for applications demanding high efficiency and compact footprints. The series utilizes proprietary control methods to maintain performance under varying load conditions while supporting small inductor designs.
Replacement Considerations
Consult official documentation for qualified substitute part numbers. Verify pin compatibility and electrical specifications before substitution. Ensure any alternative component meets the same thermal and regulatory standards.
