Flyback (42V LED @ 700mA) for LED driver
View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
The PMP5170 reference design uses the UCC28610 green-mode controller to drive a 42V string of LEDs with 700mA. The output of the driver is electrically isolated from the input. The input is from an external 400VDC source. The quasi-resonant switching of the UCC28610 allows this low-cost design to achieve efficiencies over 90%.
