The PT4561A is an isolated DC/DC converter module from the PT4560 series by Texas Instruments. It accepts a wide input voltage range of 36V to 75V (48V nominal) and provides a single regulated 3.3V output capable of delivering up to 8A of continuous current, with a total output power of 30W. The module features 1500VDC input-to-output isolation and is designed for commercial ITE (Information Technology Equipment) applications.
The converter includes an under-voltage lockout (UVLO) for reliable startup and shutdown. Additional protection features include output current limiting, short-circuit protection, and over-temperature shutdown. The device also provides differential remote sensing for improved load regulation and a remote on/off control. An external 330µF electrolytic capacitor is required on the output for proper operation.
Housed in a 19-pin single in-line package (19-SIP) with through-hole, right-angle mounting, the PT4561A is designed for easy integration into board-level power architectures. The operating temperature range spans -40°C to 85°C, and typical efficiency is 80%.
