An evaluation module and an associated user’s guide are available. The UCC28221 is used in a two-channel
interleaved Forward design converting from 36-V to 76-V dc input voltage to a regulated 12-V dc output. The
power module has two isolated 100 W forward power stages operating at 500 kHz, which are operating 180
degrees out of phase with each other allowing for output current ripple cancellation and smaller magnetic
design. This design also takes advantage of the UCC28221’s on-board 110-V internal JFET start up circuit that
removes the need of an external trickle charge resistor for boot strapping. This circuit turns off after auxiliary
power is supplied to the device conserving power.
