Overview
The BD9673EFJ-E2 is a flexible step-down switching regulator with an integrated power MOSFET, manufactured by Rohm Semiconductor. It operates as a non-isolated DC/DC buck converter with a single output. The device supports an input voltage range of 7V to 24V and provides a fixed 5V output. It delivers a maximum output current of 1.5A. The internal switching frequency is set at 300kHz. This component is designed for efficient power conversion in compact applications requiring stable regulated voltage from higher input sources.
Feature Summary
- Integrates a power MOSFET within the regulator package to reduce external component count
- Utilizes flexible step-down topology for efficient voltage conversion
- Provides a fixed 5V output suitable for standard logic supply rails
Applications
- Evaluation of DC/DC buck converter performance using the BD9673 controller
- Power supply design for industrial equipment requiring 5V regulation
- Development of portable devices needing efficient step-down conversion from 7-24V inputs
Procurement Notes
Verify the exact suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Confirm RoHS3 compliance status if required by your assembly process. Check for end-of-life notifications or recommended new designations (NRND) before finalizing procurement plans.
Selection Notes
Select this component when a fixed 5V output is required from a 7V to 24V input source with up to 1.5A load capacity. The integrated MOSFET simplifies layout compared to discrete solutions. Ensure the application environment stays within the specified operating temperature range and that the 300kHz switching frequency aligns with electromagnetic interference constraints.
