Note: Note: the min. distance of the bonding pads between input grounding and output grounding shall be ≥ 2mm.
4. Input current
When the electricity is provided by the unstable power supply, please make sure that the range of the output voltage fluctuation and the
ripple voltage of the power supply do not exceed the indicators of the modules. Input current of power supply should afford the flash startup
current of this kind of DC/DC module(see Fig. 5).
Generally: Vin=5V Iave =1400mA
Vin=12V Iave=620mA
Vin=24V Iave=310mA
Vin=48V Iave =150mA
