Class 4 - Wide Input Range 15W Power over Ethernet (PoE) Converter
TIDA-00091: 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.
PMP6584 Class 4- High power PoE, active clamp forward converter 8V@3A | TI.com
PMP6584: PMP6584 is a high power (non-standard) Power Over Ethernet (POE) active clamp forward converter. It features the TPS23756, which is a combination of a POE Powered Device (PD) controller and PWM controller. It also utilizes an ISO721 digital isolator and TPS28225 synchronous MOSFET driver. The input accepts standard POE voltage or a 24VDC-48VDC auxiliary voltage. The output power is an isolated 8VDC at 3A.
PMP6659 Class 4- Wide Input Range 15W PoE Converter | TI.com
PMP6659: PMP6659 is a flyback converter with synchronous rectification. It accepts input voltages of 10.8-57VDC/18-32VAC/PoE and has a 12V/1.25A output. This input and output combination is typically required for PoE security cameras. The synchronous rectifier provides excellent efficiency with the wide input voltage range.
