DEMO MANUAL DC2429A
6V to 20V input power supply voltage must be 350mV greater than
the higher of 6V or the desired variable, 200mA output voltage.
Up to 1.4A current consumption.
LEDs D1-D4 illuminate when power supplied.
To avoid coupling between input and output supplies it is best to
use shielded power supply cables.
See schematic.
JP5 selects output voltage
Jacks
