PH300A280-28/T

Product Overview

The PH300A280-28/T from TDK-Lambda is an isolated module DC DC converter with one 28V output, rated for 300W and up to 10.8A. It accepts a 200V to 425V input, provides 3kV isolation, and is offered in a through-hole half-brick package for board-level power conversion in commercial information technology equipment.

Key Features

• Isolated module DC DC converter with a single 28V output and a 300W power rating.
• Input range of 200V to 425V.
• Maximum output current of 10.8A at 28V.
• 3kV isolation rating for separated input and output domains.
• Remote on/off control, overcurrent protection, and overvoltage protection.
• Through-hole half-brick package, 61.0mm x 57.9mm x 12.7mm.
• -40°C to 100°C operating temperature and 91% efficiency.

Applications

• Commercial information technology equipment requiring an isolated 28V board-level supply.
• Through-hole half-brick board architectures using a 200V to 425V input and 28V output.
• Loads needing remote on/off control with overcurrent and overvoltage protection.

Design & Procurement Notes

When selecting this model, confirm that the system input remains within 200V to 425V and that the 28V rail can operate at up to 10.8A within the 300W module rating. The 3kV isolation and through-hole half-brick package affect PCB layout and mechanical mounting, so review the 61.0mm x 57.9mm x 12.7mm envelope early in board planning. The 91% efficiency and -40°C to 100°C operating range should be considered with ambient temperature and nearby components. Remote on/off, OCP, and OVP can support control and protection functions, but their use should be validated in the final application.
