9 Power Supply Recommendations

The DCR02 is a switching power supply, and as such can place high peak current demands on the input supply. To avoid the supply falling momentarily during the fast switching pulses, ground and power planes must be used to connect the power to the input of DCR02. If this connection is not possible, then the supplies must be connected in a star formation with the traces made as wide as possible.
