The Picotest LM20143 Point of Load Regulator Board is a cutting-edge demonstration platform for integrated synchronous buck regulation. This compact, self-contained unit showcases a 5V input and 1.2V/2.5A output configuration, leveraging emulated current mode control for straightforward flat impedance output creation.
Designed with accessibility in mind, the board features easily customisable 0805 chip size components, enabling engineers to experiment with various values. Powered via USB and equipped with an on-board resistive load, this demo board offers a complete testing environment for power regulation scenarios.
The LM20143 board is engineered for comprehensive analysis, incorporating provisions for Bode plot measurements. It includes a pre-installed injection resistor (R5) and dedicated test points (TP3 and TP4) for injection signal and measurement. SMA output connectors further enhance its versatility, facilitating connections for a wide range of measurements, including 2-port output impedance and step load tests.
