BP5319

Special Purpose Regulators Overview

The BP5319 is a DC-DC regulated power supply module manufactured by ROHM Semiconductor. It operates with a nominal input voltage of 5 V, supported by a minimum of 4.5 V and a maximum of 5.5 V. The device provides a single output within a one-function configuration. It utilizes a SIP7/9 package with nine terminals and measures .24 inches in size. The component is lead-free, RoHS compliant, and classified under EAR99. It functions as a specialized PMIC designed for -24V applications.

Special Purpose Regulators Feature Summary

• Integrated DC-DC conversion capability within a compact module form factor
• Single-output regulation for stable power delivery
• Compliance with lead-free and RoHS environmental standards

Special Purpose Regulators Applications

• General purpose DC-DC power conversion systems
• Embedded power management modules requiring single output regulation
• Specialized PMIC applications operating near 5V input

Special Purpose Regulators Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as documentation references both BP5319 and BP5319 X. Confirm the terminal count matches your PCB footprint requirements, as sources indicate variations between seven and nine terminals. Ensure the supplier provides the official ROHM datasheet to validate the exact electrical characteristics and pinout configuration before integration into the design.

Special Purpose Regulators Selection Notes

Select this component when a pre-configured DC-DC module is preferred over discrete designs. It suits applications requiring a fixed 5V input range and a single regulated output. Consider the SIP7/9 package dimensions for board space constraints. Verify that the -24V application context aligns with the system's voltage requirements. This part is suitable for general industrial or consumer electronics where module simplicity reduces design complexity.

Special Purpose Regulators Part Context

The BP5319 belongs to ROHM's Power Management Specialized (PMIC) product line. It is categorized as a DC-DC converter module rather than a standalone IC. The component is distinct from other ROHM parts like the RB531CM-30T2R diode or BD5319G-2C detector. It represents a modular solution for power conversion, differing from integrated circuit-based regulators by offering a complete functional unit in a small outline package.

Special Purpose Regulators Replacement Considerations

No public confirmed substitute part numbers are available for the BP5319. Designers should consult ROHM directly for equivalent module recommendations if this specific part becomes unavailable.
