LTC4263IDE#PBF PMIC - Power Over Ethernet (PoE) Controllers

The LTC4263IDE#PBF is a Power over Ethernet (PoE) controller for Power Management Integrated Circuits (PMICs). It is designed to support the IEEE 802.3af (Power over Ethernet) and IEEE 802.3at (High Power) standards. This highly efficient, power management IC allows power to be delivered to both powered devices (PDs) and lower-power devices. The LTC4263IDE#PBF can provide a maximum input power of up to 60 watts and can support up to 16-ports.

Design Overview

The LTC4263IDE#PBF uses its integrated Power Management Unit (PMU) to efficiently manage power across the system. This PMU includes a high efficiency DC/DC converter that provides both 5V and 12V outputs and a 12V LDO that reduces the system\'s power consumption. It also includes power control, current monitoring, and fault detection circuitry. The device also supports up to 8 Ethernet ports with a maximum of 8 PDs.

Features

The LTC4263IDE#PBF supports a wide range of features designed to make it easier to manage power. It includes support for a range of Ethernet speeds, including 10 Mbps, 100 Mbps, and 1,000 Mbps. It also includes support for PoE, power monitoring, and fault detection, as well as safe and secure current flow. It also protects PDs from voltage and current overloads, as well as ESD protection. The device also supports external thermal protection to ensure that PDs are not subjected to excessive heat. The LTC4263IDE#PBF also includes a power-saving Mode and a Sleep Mode that can reduce power consumption by up to 95%.

Application Fields

The LTC4263IDE#PBF is a highly versatile power management controller that can be used in a variety of applications. It has been widely used in access points, IP cameras, and other high-power networking applications. It can also be used in automotive, industrial, and medical applications. The high efficiency of the device ensures that it can provide power for a wide range of devices.
