<p>The LM20143EVAL evaluation board is a DC/DC and AC/DC (off-line) switched mode power supply (SMPS) solution for remote sensing, remote-accelerometer, remotesensing, power-line applications or any other RF application requiring low-noise power. The LM20143EVAL evaluation board offers several advantages over linear competitors, including lower power dissipation, high efficiency, and improved light load performance.</p><p>The LM20143EVAL evaluation board includes a DC/DC and AC/DC converter topology. The DC/DC converter consists of a fixed frequency integrated circuit (IC) operating in a buck, boost, or buck-boost circuit. The AC/DC converter consists of two boost circuits operating in series. The switching frequency of the LM20143EVAL evaluation board is programmable, allowing the user to optimize the performance of the board. The LM20143EVAL evaluation board also includes integrated inductors, capacitors, and thermistors to optimize the performance of the board when operated in various signal and power conditions.</p><p>The objective of the LM20143EVAL evaluation board is to convert high input voltage levels into regulated low output voltage levels with minimal power dissipation and high efficiency. To achieve this, the LM20143EVAL evaluation board utilizes the topology shown in the figure below, which incorporates several key components.</p> <p><img src="img/LM20143EVAL_Application_Field_and_Working_Principle.jpg" alt="LM20143EVAL Application Field and Working Principle" width="500"></p><p>The main components of the LM20143EVAL evaluation board are the primary power switch, secondary switch, and the main controller. The primary power switch, also known as the high-side transistor, is responsible for controlling the input voltage by switching the voltage between the input and the output. The secondary switch, also known as the low-side transistor, is responsible for controlling the output voltage by regulating the amount of current flowing between the input and output. The main controller, also known as the current-sensing controller, is responsible for monitoring the voltage level on the output side of the board.</p><p>In addition to these components, the LM20143EVAL evaluation board also includes integrated inductors, capacitors, and thermistors to optimize the performance of the board. The inductors help reduce the voltage ripple on the output side of the board, while the capacitors provide a clean power supply. The thermistors help maintain a stable temperature on the board, which helps reduce power dissipation.</p><p>The working principle of the LM20143EVAL evaluation board is simple. In order to convert a high input voltage into a regulated low output voltage, the input voltage is switched between the output and the input of the board by the primary power switch. This in turn causes the current flowing through the inductors to increase, which in turn reduces the voltage ripple on the output side of the board. The main controller then regulates the current flow, thereby controlling the output voltage and ensuring a stable power supply.</p><p>In conclusion, the LM20143EVAL evaluation board is a DC/DC and AC/DC (off-line) SMPS solution for remote sensing applications or any other RF application requiring low-noise power. The LM20143EVAL evaluation board offers several advantages over linear competitors, including lower power dissipation, high efficiency, and improved light load performance. The LM20143EVAL evaluation board utilizes switch-mode topology combined with integrated inductors, capacitors, and thermistors to optimize the performance of the board.</p>
