The LTC4259ACGW-1#PBF is a member of a group of PMIC (Power Management IC) components designed to facilitate the delivery of power over Ethernet (PoE) cables. As an integrated circuit, it primarily chairs the function of regulating the power supply and current delivered over an Ethernet cable. Additionally, this component is designed to provide an efficient connection and better utilization of existing cables.

The LTC4259ACGW-1#PBF is primarily used in Power-over-Ethernet controllers, where Ethernet cables facilitate the delivery of power from a power source to appliances. Among this component’s main features is impedance-based voltage control that serves to protect the component from damage due to excessive current or power loss. This component also includes reverse-level meter detect (RLMD) capabilities that alert a user whenever current levels exceed a pre-set threshold. The component also includes thermal-foldback (TFB), which is used to detect voltage spikes caused by component failure, and then reduce the current output in order to protect the component from damage.

The LTC4259ACGW-1#PBF supports a wide range of operating conditions. It is designed to operate at temperatures between – 40C and +85C, with a wide ±18V to ±75V operating range. Additionally, it is capable of supplying both 25.5V and 305V at a maximum operating frequency rate up to 25MHz. This component provides a high efficiency of 91%, with a low output quiescent current of as little as 6.5mA. This combined with a low average output ripple size of less than 1MHz, makes this component a dependable choice in Power-over-Ethernet applications.

The LTC4259ACGW-1#PBF is able to accommodate a variety of signal types, including non-PoE-compliant signal connections, PoE Plus signal connections, and even encrypted signals. It is designed to provide a secure connection between the power supply and the appliance while allowing for a maximum power delivery up to 120W. Additionally, this component is designed to be compatible with most existing Ethernet switches.

The LTC4259ACGW-1#PBF is a highly-reliable and efficient component used in Power-over-Ethernet applications. It contains a number of features for regulating the power supply and current delivered over an Ethernet cable. It is capable of accommodating a variety of signal types, providing a secure connection between the power supply and the device, and supporting a wide range of operating conditions. As a result, it is a dependable choice for Power-over-Ethernet designs.
