Isolated power supply with 3.3V input and 12V (15V) output

 
Overview


The Riversdie design (MAXREFDES8#) uses an H-bridge transformer driver ( MAX256 ) and an LDO ( MAX1659 ) to convert a 3.3V input to an isolated 12V (15V) output supply (Figure 1). This versatile power supply solution can be used in a variety of isolated power supply applications, but is primarily targeted at industrial sensors , industrial automation, process control, and medical electronics .
