Overview
The BD1482EFJ-E2 is a synchronous buck converter from ROHM Semiconductor, housed in an HTSOP-J8 package. It operates with an input voltage range of 4.2 V to 18 V and delivers up to 2 A output current. The adjustable output voltage spans from 923 mV to 12.6 V. Operating at a fixed switching frequency of 380 kHz, the device features a shutdown function and draws 1.2 mA of operating supply current. It supports an industrial temperature range from -40°C to +85°C.
Feature Summary
- Integrates power MOSFETs for compact synchronous buck conversion
- Includes shutdown control for power management
- Supports wide input voltage ranges for flexible system design
Applications
- Portable electronic devices requiring efficient step-down regulation
- Industrial equipment power supplies
- Communication infrastructure systems
Procurement Notes
Verify component authenticity through authorized channels due to the NRND status. Confirm package integrity upon receipt as the HTSOP-J8 form factor requires careful handling. Cross-reference datasheet revisions to ensure compatibility with existing designs. Check for RoHS compliance documentation if required by specific regulatory standards.
Selection Notes
Select this component when a synchronous buck topology is preferred for higher efficiency compared to asynchronous alternatives. The integrated FETs reduce external component count. Ensure the 380 kHz switching frequency aligns with EMI constraints and inductor selection requirements. Verify that the 2 A current rating meets peak load demands within the specified thermal envelope.
