MP8030
DESCRIPTION
The MP8030 is a fully integrated, IEEE 802.3af/at/bt-pliant, Power over Ethernet (Po E), 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 highpower applications (>51W). The GATE2 driver supports an external, low on resistance Nchannel MOSFET to prevent high power loss when 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 also can 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...
