EVL8009-V-00H

EVL8009-V-00H is an evaluation board designed to demonstrate the capabilities of the MP8009, an integrated, IEEE 802.3af/at power over Ethernet (PoE), powered device (PD) power supply converter. It also includes a PD interface and a highly efficient flyback/forward controller. The PD interface features all IEEE 802.3af/at capabilities, including detection, 1-event classification, 2-event classification, a 120mA inrush current limit, an 840mA operation current limit, and a 100V hot-swap MOSFET. The flyback/forward controller is a low-cost, small-sized, isolated solution with primary-side regulation (PSR) for flyback applications. The controller can also be used for SSR flyback topologies. It is available in QFN-28 (4mmx5mm) package. Typical applications include IEEE 802.3af/at-compatible devices, security cameras, video phones, wireless local area network (WLAN), access points and internet of things (IoT) devices.

• 36V to 57V power over Ethernet (PoE) input or 48V auxiliary adapter input
• 12V output voltage (VOUT), 2.1A output current (IOUT)
• Primary-side regulation (PSR) for flyback applications
• 802.3af/at-compatible
• Frequency dithering for electromagnetic interference (EMI) reduction
• Overload protection (OLP), short-circuit protection (SCP)
• Overvoltage protection (OVP) with hiccup mode for each protection, thermal shutdown
• Optimized performance with MPS MPL-AL5050 inductor series
• Can support a PoE-PD front-end solution with minimal external components
• High-efficiency secondary-side regulation (SSR) for active-clamp forward applications
