Shenzhen Mingjiada Electronics Co., Ltd. New and Original Supply PMIC MP8030GQJ-Z Power over Ethernet - PoE, Fully Integrated, 802.3af/at/bt Compliant PoE PD Interface with High Efficiency Flyback/Forward Controller

Overview

The MP8030GQJ-Z is a fully integrated, IEEE 802.3af/at/bt compliant Power over Ethernet (PoE), Powered Device (PD) power converter. The device features a PD interface and a high efficiency flyback/forward controller.

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

Features

- 802.3af/at/bt compliant

- Internal hot-swappable MOSFETs for ≤51W designs

- External FET with GATE1 for >51W designs

- GATE2 N-Channel MOSFET Driver for Adapter Power Supplies

- Supports auto-classification

- Automatically maintains power characterisation

- Supports flexible topologies through DC/DC design:
