The PMP4986 reference design uses the UCC2581 PWM controller to generate an isolated 3.3V/300mA output. Three TPS62110 converters are used to create +/-2.5V and 1.2V outputs from the 3.3V output. A TPS54060 is used on the primary side to create a non-isolated 3.3V/12mA output. The TPS62110 converters can be synchronized to an external 1MHz clock. The UCC2581 and TPS54060 supplies can be synchronized to an external 125kHz clock through the ISO7242.
