Product Details

Demonstration circuit 2125 is a small, highly-integrated, non-isolated PoE Powered Device (PD) solution. It features a PD Interface Controller (LT4275), which interfaces with a PoE Power Sourcing Equipment (PSE), an ideal diode bridge controller (LT4321), which minimizes bridge losses, and a DC/DC μModule® regulator (LTM8027).

Product Details

Demonstration circuit 1307B features the LTM8027 configured to deliver 12V/4A from a 16V to 60V input. The wide input range of the LTM8027 allows a variety of input sources such as automotive batteries, wall adaptors and industrial supplies. The LTM8027 is a step down converter, so a minimum amount of headroom is required to keep the output in regulation. A soft-start feature controls the output voltage slew rate at start-up, reducing current surges and voltage overshoots.
