LTC4266AIUHF-1#PBF

The LTC4266AIUHF-1#PBF is a highly integrated, low-voltage, single-channel power over ethernet (PoE) controller. The device provides an integrated power supply solution, integrated IEEE 802.3af and 802.3at, pulse-width modulation (PWM)control, dual-channel system control logic,andon-chip fault protection. This all-in-one packageticallyaddresses the challenges andcosts involvedin building power over ethernet (PoE) applications.

Typical applications of the LTC4266AIUHF-1#PBF include providing power to remote video surveillance cameras, wireless access points and other powerover ethernet (PoE) devices.The device is designed for use inPoE applications that require a low-profile, low-voltage, single-channel power delivery system.

The LTC4266AIUHF-1#PBF follows an adjustable, MOSFET-controlled, 3-phase interleaved boost converter topology to efficiently deliver power over ethernet (PoE). Using the integrated IEEE 802.3af and 802.3at compliant devices, the LTC4266AIUHF-1#PBF is optimized to provide 12.95W of power to remote devices on the IEEE 802.3af PoE line.

The integrated dual-channel system control logic of the LTC4266AIUHF-1#PBF enables it to be programmed and configured to support different operating modes or control protocols. Users can configure the device to operate in a constant voltage mode or a constant current mode. The pulse-width modulation (PWM) control enables users to achieve fast transient response in different applications.

The LTC4266AIUHF-1#PBF also features integrated protections, including overvoltage protection (OVP) and overcurrent protection (OCP). It also offers a built-in in-rush current limiter, which can reduce the in-rush current spike and increase the peak capacitor charging current limit. The device also provides thermal shutdown protection, so that the system is protected against high temperature events.

The LTC4266AIUHF-1#PBF is a highly integrated, low-voltage, single-channel power over ethernet controller that is designed for use in PoE applications that require a low-profile, low-voltage delivery system. Utilizing an adjustable, MOSFET-controlled, 3-phase interleaved boost converter topology, the LTC4266AIUHF-1#PBF is capable of delivering up to 12.95W of power over ethernet. In addition, is equipped with integrated IEEE 802.3af and 802.3at compliant devices, dual-channel system control logic, pulse-width modulation (PWM) control, and several built-in protections to protect the system from high-temperature events and other faults.
