... DC voltage will develop on V above 45V, the N-channel MOSFET is turned off. The maximum gate voltage for the external MOSFET is 24V. The unregulated voltage is approximately 18V. The SR036 also provides a regulated 3.3V whereas the SR037 provides a regulated 5.0V. WARNING!!! Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line ...

... Fuse 120VAC or 240VAC Figure 2: Example Circuit with Enable Control Figure example circuit using the SR036 or SR037 along with a Supertex VN2460N8 MOSFET to generate an unregu- lated voltage of approximately 18V and a regulated voltage of 3.3V for the SR036 or 5.0V for the SR037. The combined total Fuse ...

... Figure 4: Driving 12V Relay Coils The circuit shown in Figure 4 uses the SR036 to supply a regulated 3.3V for the logic control circuitry while the unregu- lated voltage is used to drive a 12V relay coil. The operating voltage for a 12V relay coil is typically very wide and can therefore operate directly from the unregulated line ...
