We need a DC/DC Converter to supply a small board. The available power supply is DC, between 48V and 50V and the current is 7mA.
Our board requires 12V-6mA power supply in sleep mode. In full operation, which is only for a few times during a day and only for some 20secs each time, our board requires 12V-20mA.
Could you propose me something to start my research from? Preferably easy to use and cost effective part.
