Overview
The BD8628EFV-E2 is a switching voltage regulator IC from ROHM Semiconductor, classified under PMIC - Voltage Regulators - DC DC Switching Regulators. It functions as a buck converter with a positive fixed output of 5V and a maximum output current of 3A. The device is housed in a 24-VSSOP package with an exposed pad, measuring 0.220 inches (5.60mm) in width. It operates within a temperature range of -45°C to +85°C and supports surface mount installation.
Feature Summary
- Integrated buck switching regulator topology for efficient DC-DC conversion
- Fixed 5V output configuration with 3A current capability
- Compact 24-pin VSSOP package design with exposed thermal pad
Applications
- Portable electronic devices requiring stable 5V power rails
- Embedded systems utilizing buck conversion architectures
- Consumer electronics powered by higher input voltage sources
Procurement Notes
Verify the exact suffix E2 against official ROHM documentation to confirm pinout and compliance status. Confirm lead-free specifications and moisture sensitivity levels prior to assembly. Check for recent lifecycle notifications such as NRND or EOL status directly from the manufacturer to ensure long-term supply availability.
Selection Notes
Select this component when a fixed 5V output at 3A is required in a compact form factor. Ensure the input voltage exceeds 5V to maintain proper buck regulation. Verify that the thermal performance of the 24-VSSOP package with exposed pad meets the system's heat dissipation requirements under full load conditions.
Part Context
This part belongs to the BD8628 series of switching regulators manufactured by ROHM Semiconductor. It is categorized within Power Management ICs specifically designed for voltage regulation applications. The device shares similar packaging and functional characteristics with other members of the BD86xx family, tailored for space-constrained designs.
Replacement Considerations
Consult ROHM datasheets for direct pin-compatible alternatives within the BD862x series. Verify electrical parameters such as output current and voltage stability before substituting with generic buck converters. Ensure any replacement matches the 24-VSSOP package dimensions and thermal pad configuration.
