Monolithic Power Systems (MPS) MP8009 Flyback/Forward Controllers
Monolithic Power Systems (MPS) MP8009 Flyback/Forward Controllers are integrated IEEE 802.3af/at PoE compliant powered device (PD) power supply converters. The MP8009 interface comprises all IEEE 802.3af/at functions, including detection, 1-event and 2- event classification, 120mA inrush current limit, 840mA operation current limit, and a 100V hot-swap MOSFET.The MPS MP8009 Flyback/Forward Controllers are a space-saving isolated solution with primary-side regulation (PSR) for flyback applications and high-efficiency secondary-side regulation (SSR) for active clamped forward applications.
The MP8009 delivers a front-end solution for PoE PD applications with minimal external components. The device offers Hiccup Protection for Overload Protection (OLP), Short-Circuit Protection (SCP), Over-Voltage Protection (OVP), and Thermal Shutdown.
The MP8009 is housed in a QFN-28 (4mm x 5mm) package with a 250kHz fixed switching frequency.
