9 Power Supply Recommendations
The input supply range must be at least 6 V and should be below 26 V. An input capacitor of 4.7 µF (typical) is
required as well. Current requirements will be set by the required current from the solenoid.
10 Layout
10.1 Layout Guidelines
The trace for the solenoid or relay current should be wide in order to prevent any unexpected voltage drop. Diode
placement should not be far from the inductor and both should be placed close to the output.
