| The Lakewood design (MAXREFDES7#) uses an H-bridge transformer driver ( MAX256 ) and a pair of low-dropout linear regulator LDOs ( MAX1659 ×2) to generate an isolated supply of ±12V (±15V) output from a 3.3V input (Figure 1). This universal power supply solution can be used in many different types of isolated power supply designs, but is primarily targeted at applications such as industrial sensors , industrial automation, process control, and medical equipment . |  More pictures (PDF, 1.9MB) |
