(...) Yes, P=VI. When the Specification sheet says the converter can source 1W, they mean at most 1 Watt. When your sensor says it consumes 35mA, this is again the max and only if the 12V is supplied. If less than 12V is supplied it will probably (...)

Hi, I intend to use a 5V source battery going thru a DC to DC converter to get a 12V source. Then this 12v will connect to my diffuse sensor which operrate at 12V. The sensor's current consumption maximum is 35mA. If the output Watt of the DC-DC (...) (26 years ago, 18-Mar-99, to lugnet.robotics.handyboard)
