Board Overview

Figure 2. Board Overview

The board consists basically of eight sub-circuits:

•

An input filter to reduce the noise of the buck converter on the input cabling as well as active reverse-
polarity protection

•

A synchronous buck converter providing the power for the output

•

A VID interface to adjust the output voltage of the buck converter

•

A trigger circuit providing an external trigger signal when a pulse is generated, as well as a trigger
input to start a pulse from an external signal source

•

A user interface with push-buttons and LEDs
