SLUSCR9B June 2017 – December 2020 UCC28730-Q1
PRODUCTION DATA
A typical application for the UCC28730-Q1 includes the compatible UCC24650 Wake-Up Monitor device to regulate an isolated low-voltage DC output with low output capacitance. When the UCC28730-Q1 is operating in the low-frequency Wait state, the UCC24650 alerts the UCC28730-Q1 to a sudden load increase, avoiding the need for extremely high output capacitance to hold up between power cycles. As shown in Figure 8-1, the output rectification uses a ground-referenced diode to facilitate application of the UCC24650. A ground-referenced synchronous rectifier may also be used.
This figure is simplified to illustrate the basic application of the UCC28730-Q1 and does not show all of the components and networks needed for an actual converter design, nor all of the possible circuit variations.
