This reference design provides an isolated 15-V and 22-W outputs with flyback topology with LM51561-Q1 controller. The power supply can be powered from the 200-V to 480-V DC input. This primary-side regulation design does not contain an optocoupler and uses a dual random spread spectrum which reduces EMI.
