TPS23731RMTR General Description

One of the standout features of the TPS23731RMTR is its advanced startup capability with adjustable soft-start. This feature not only simplifies the converter startup process but also ensures compliance with IEEE 802.3bt/at startup requirements. Additionally, the soft-stop feature reduces stress on switching sync FET(s), leading to potential cost savings on FET components. The PSR functionality of the DC-DC controller eliminates the need for external shunt regulators and optocouplers by utilizing feedback from an auxiliary winding for precise output voltage control

Key Features

This is a unique feature
Enables power monitoring and control
Optimizes system efficiency significantly
