Descripción
- PMP4298, Reference Design Using UCC28051 is a boost transition mode power factor corrector (PFC), which can rectify an AC input line voltage to 380V DC, the resonant LLC stage UCC25600 regulates the output to 24V/2A for an audio amplifier with feedback to the LLC controller and 48V for the LED driver input. The flyback with UCC28610 in parallel generates 5V/3A for the system board and 5V/1A for standby power. In the LED driver stage, the 48V input voltage requires another front end boost stage to boost the output voltage to 80V, which connects to the eight-channel TLC5960 with 20LEDs at 120mA per string. This technique is the most common type of current LED backlight, the LLC design is easily implemented. The intelligent headroom voltage monitor automatically minimizes the power loss caused by the LED forward voltage change
