DPA423R

DPA423R Description

The DPA423R from Power Integrations is a high-performance, surface-mount switching regulator designed for demanding Power over Ethernet (PoE), telecom, and DC-DC converter applications**. This single-output regulator delivers a robust 220V output voltage with a wide input voltage range of 16V to 75V, making it suitable for industrial and communication systems requiring stable power conversion. Packaged in a TO263-7C (D2PAK) tube, the DPA423R complies with REACH Unaffected and EAR99 regulations, ensuring environmental and export compliance. With a Moisture Sensitivity Level (MSL) of 4 (72 hours), it demands careful handling during assembly.

DPA423R Features

• Wide Input Range (16V–75V): Supports flexible power sourcing in variable voltage environments.
• High Output Voltage (220V): Ideal for PoE and telecom systems requiring elevated voltage levels.
• Surface-Mount (TO263-7C): Compact footprint for space-constrained PCB designs.
• Robust Compliance: Meets REACH Unaffected and EAR99 standards for global deployment.
• Active Product Status: Guaranteed availability and manufacturer support.
• Low Moisture Sensitivity (MSL 4): Requires controlled storage but ensures reliability post-assembly.

DPA423R Applications

• Power over Ethernet (PoE): Powers high-voltage endpoints like IP cameras, wireless access points, and VoIP phones.
• Telecom Infrastructure: Voltage regulation for base stations, routers, and optical network units.
• Industrial DC-DC Converters: Efficient power management in automation, motor drives, and test equipment.
• Specialty Power Supplies: Custom designs needing high-voltage, single-output regulation with minimal footprint.
