# Title: LM20143 Point of Load Regulator Demo Board


## Description: The circuit is an integrated point of load synchronous buck regulator with a 5V input and a 1.2V/2.5A output. The device uses emulated current mode control, making it simple to create a flat impedance output. Easily accessible 0805 chip size components make it easy to customize or experiment with different component values. This is a fully self-contained demo board using USB input power and an on-board resistive load. Supported Measurements TEST SIGNAL INJECTORS NEEDED 2-port output impedance J2102A two SMA cables (optional two P2130A or J2130A) Load Step J2111A or J2150A and J2130A or P2130A SMA cable Ripple and Noise J2130A or P2130A SMA cable Turn on overshoot Scope with probe or SMA cable PSRR J2120A or J2111A and two voltage probes Input Impedance J2120A voltage and current probe Bode Plot J2100A or J2101A two voltage probes
