The PT4851A from Texas Instruments is a triple-output isolated DC-DC converter module designed for mixed-logic applications. It provides three independently regulated outputs: 3.3V at 15A, 2.5V at 10A, and 1.5V at 10A, delivering a combined power of 49W. The converter operates from a standard telecom input voltage range of 36V to 75V and offers 1500VDC isolation.
Key protection features include over-current, over-voltage, over-temperature shutdown, and under-voltage lockout (UVLO). The module exhibits a typical efficiency of 85% and can operate over a wide temperature range of -40°C to 85°C.
The PT4851A is housed in a 26-SIP module with through-hole, right-angle mounting, requiring no external heatsink. It belongs to the Excalibur PT4850 series and is suitable for powering DSPs, ASICs, and I/O logic in telecom and industrial equipment.
