IRISMPS3 General Description

The IRISMPS3 reference design is a complete tested power supply circuit. It is designed for a universal AC line input and will provide a 15V, 4A full load DC output.

The design uses a flyback converter topology, with an IRIS4013K as the main switch and control device. The initial start-up current for the IRIS4013K is provided by a dropper resistor from the DC bus. Once the circuit is started the Vcc power for the IRIS4013K comes from the bias winding of the main transformer. The primary current control circuit consists of a current sensing resistor which feeds a voltage proportional to the transformer primary current into the feedback (FB) pin of the IRIS4013K. The secondary voltage control loop uses an LM431 precision shunt regulator as the reference and an optocoupler to feedback the information across the transformer galvanic isolation boundary back to the control circuit of the IRIS4013K.
