LM20145 Demonstration Board
Description
The LM20145 demonstration board has been designed to balance overall solution size with the efficiency of the regulator. The demonstration board measures just 1.0 x 1.0" on a two layer PCB: with all components placed on the top layer. The power stage and compensation components of the LM20145 demonstration board have been optimized for an input voltage of 5V: but for testing purposes: the input can be varied across the entire operating range. The output voltage of the evaluation board is nominally 2.5V. The control loop compensation of the LM20145 demonstration board has been designed to provide a stable solution over the entire input and output voltage range with a reasonable transient response. The EN pin is connected to VIN through a 100kOhm resistor which will enable the device when power is applied."
