产品概述

描述

The PM8803 integrates a Power over Ethernet (PoE) interface and a current mode PWM controller to simplify the design of the power supply sections of all powered devices. The PoE/PoE+ interface includes all functions required by the IEEE 802.3at as well as detection, classification, undervoltage lockout (UVLO) and inrush current limitation. The PM8803 specifically performs IEEE802.3at Layer 1 hardware classification, providing the system with an indication of Type 2 PSE successful detection.
The PM8803 has been designed to work with power either from the Ethernet cable or from an external power source such as a wall adapter, ensuring the priority of the auxiliary source over the PoE. The DC-DC section of the PM8803 features a programmable oscillator frequency, an adjustable slope compensation, dual complementary low-side drivers, programmable dead time and an internal temperature sensor.
The PM8803 targets high-efficiency conversion under all load conditions supporting flyback, forward, forward with active clamp converters and synchronous rectification.
