This module supports PMBus communication and parallel operation without the need for an external ORING FET, making it ideal for applications such as optical transmission, data networks, servers, and telecommunications.
The T31SN12008 is a 100W non-isolated 1/32-brick DC-DC power module from Delta’s T31SN series. Designed to provide a flexibly adjustable, stable output (3.3–16.5V) across a wide input voltage range (9–53V), it is suitable for point-of-load power supply in communications, computing, and industrial equipment, with a peak efficiency of up to 98%.
The T31SN24005 is also a 100W non-isolated 1/32-brick module that uses an industry-standard DOSA package. It supports a wide input range of 9V–53V and an adjustable output range of 5V–30V, with a peak efficiency of up to 98%. This module can be used with 12V, 24V, 36V, or 48V AC-DC power supplies and is suitable for applications in the medical, telecommunications, industrial, and test and measurement equipment sectors.
In addition, Delta has launched the U50SU4P162, an ultra-high-power-density 48V/12V bidirectional DC-DC converter. Featuring a switching frequency exceeding 1 MHz and a power density as high as 3,000 W/inch³, it achieves 98% conversion efficiency, perfectly meeting the demands of advanced applications such as data centers and supercomputers.
