Description

MPL

Optimized Performance with MPS Inductor

The MP8030 is a fully integrated, IEEE 802.3af/at/bt-compliant, Power over Ethernet (PoE), powered device (PD) power supply converter. The device features a PD interface and a high-efficiency flyback/forward controller.

The PD interface has all the functions of IEEE 802.3af/at/bt. It also integrates a 100V hot-swap MOSFET for ≤51W applications and one GATE1 driver to enhance efficiency for high-power applications (>51W). The GATE2 driver supports an external, low on resistance N-channel MOSFET to prevent high power loss while the device is powered by an adapter.

The flyback/forward controller is specifically designed for primary-side regulation (PSR) flyback applications, as well as secondary-side regulation (SSR) active-clamp forward applications. It can also be used in an SSR flyback topology.

The MP8030 features overload protection (OLP) with hiccup mode, short-circuit protection (SCP), over-voltage protection (OVP), and thermal shutdown.

The MP8030 is available in a QFN-32 (5mmx6mm) package.

Optimized Performance with MPS Inductor

The EVL8030-QJ-00B is an evaluation board designed to demonstrate the capabilities of the MP8030, a fully integrated, IEEE 802.3af/at/bt compatible, power over Ethernet (PoE) powered device (PD) with a PD interface and high-efficiency, primary-side regulated (PSR) flyback controller.

The PD interface has all the functions of IEEE 802.3af/at/bt. It integrates a 100V hot-swap MOSFET and a gate driver (GATE1) to improve efficiency for high-powered applications. The second gate driver (GATE2) supports the external, low on resistance (R_DS(ON)) N-channel MOSFET, which replaces the traditional diode O-ring to reduce power loss on the diode while powered by an adapter.

The flyback controller is designed for both small-sized, isolated, PSR flyback applications, as well as high-efficiency, secondary-side regulated (SSR), active-clamped forward applications. The MP8030 can also be used for SSR flyback topologies.

The MP8030 is available in a QFN-32 (5mmx6mm) package.
