Custom transformers eye USB Power Delivery 3.1 applications| Electronics Weekly

They are aimed at AC-to-DC switching power supplies and USB-C power delivery systems meeting the latest standard. Specifically, they support Extended Power Range (EPR), enabling power delivery up to 240W (48V/5A).

This is an increase over the 100W limit of previous PD 3.0 implementations, highlights ITG. Which means engineers can design power supplies for more demanding environments.

Possible applications include high-performance laptops, gaming systems, monitors, servers, and power tools.

USB PD 3.1

USB PD 3.1 incorporates additional voltage levels: 28V, 36V, and 48V – alongside adjustable voltage supply (AVS) capabilities. The company says the transformer designs specifically accommodate these higher voltages while maintaining safety, efficiency, and thermal stability.

Note that PD 3.1 systems will be backward compatible with earlier PD 3.0 and PD 2.0 devices.

The T201691B-005 provides a 65W solution within a 13mm profile, while the T201724A-01 offers a vertically mounted design within a 27.5 x 16mm footprint capable of handling 140W of power delivery.

Custom transformers

The new transformers address the growing demand for higher power in a compact design, says the company.

“These new transformer designs reflect the evolving needs of USB Power Delivery as it moves into higher power applications,” said Martin Kuo, Director of Future at ITG Electronics.

“By engineering solutions that meet PD 3.1 requirements, we are enabling our customers to deliver more power in smaller, more efficient designs without compromising reliability.”
