Detailed Description for PAH350S48-28/T
Product Overview
The PAH350S48-28/T from TDK-Lambda is an isolated module DC-DC converter for board-mount power architectures. It accepts a 36V to 76V input and provides a single 28V output at up to 12.5A, corresponding to a 350 W power rating. The converter provides 1.5 kV input-to-output isolation and uses a 9-DIP module, 1/2 brick package with through-hole mounting. Control and protection functions include remote on/off with an active-low enable, overcurrent protection, and overvoltage protection. The operating temperature range is -40°C to 100°C, and efficiency is 92%.
Key Features
- Isolated single-output DC-DC conversion from 36V to 76V input to 28V output at 12.5A, rated for 350 W.
- 1.5 kV isolation between input and output.
- Remote on/off control with active-low enable.
- Includes overcurrent protection and overvoltage protection.
- Through-hole 9-DIP module, 1/2 brick package, 2.40 in L x 2.28 in W x 0.50 in H (61.0 mm x 57.9 mm x 12.7 mm).
- Operating temperature range of -40°C to 100°C and 92% efficiency.
Applications
- Commercial information technology equipment requiring a 28V board-level rail from a 36V to 76V input.
- Board-level power conversion that needs 1.5 kV input-to-output isolation in a through-hole 1/2 brick module.
- ITE systems that use remote on/off control with an active-low enable signal.
Design & Procurement Notes
Design considerations should account for the 36V to 76V input range, 28V single output, and maximum 12.5A load current when sizing input and output components. The 1.5 kV isolation rating supports separation between the input source and the 28V rail. The active-low enable and remote on/off function require a control signal interface that can assert and deassert the converter. Overcurrent and overvoltage protection should be considered in system-level fault handling. The through-hole 9-DIP, 1/2 brick package and 61.0 mm x 57.9 mm x 12.7 mm dimensions affect PCB layout, mechanical clearance, and thermal management. The -40°C to 100°C operating temperature range and 92% efficiency are relevant to thermal budgeting and power loss calculations. Procurement should verify that the board footprint, mounting method, and control signal interface match these package and control characteristics.
