Class 4 - Wide Input Range 15W Power over Ethernet (PoE) Converter
Texas Instruments
Description
Note: TIDA-00091 was implemented using hardware from PMP6659.The Class 4 – Wide Input Range: 15W Power over Ethernet (PoE) Converter reference design is intended as an evaluation module for users to develop end-products for IP security camera applications. This reference design has been optimized for its wide input voltage range; delivering an output power of 12-V at 1.25-A (15-W) from either an adapter input (10.8 to 57-VDC or 18 to 32-VAC) or power over Ethernet. The wide input voltage range makes this design compatible with legacy applications where 12- or 24-VDC: or 24-VAC auxiliary power is used.
