9 / 18 page UC2875EP PHASE SHIFT RESONANT CONTROLLER SGLS233A − FEBRUARY 2004 − REVISED DECEMBER 2008 9 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 APPLICATION AND OPERATION INFORMATION Figure 4. Oscillator Schematic, Frequency vs Resistance Graph, and Timing Diagram The high frequency oscillator may be either free-running or externally synchronized. For free-running operation, the frequency is set via an external resistor and capacitor to ground from the FREQSET pin. The CLOCKSYNC pin of the oscillator may be used to synchronize multiple UC2875 devices simply by connecting the CLOCKSYNC of each UC2875 to the others as in Figure 5. Figure 5. Synchronizing Multiple UC2875−EP Devices All ICs will sync to chip with the fastest local oscillator. R1 & RN may be needed to keep sync pulse narrow due to capacitance on line. R1 & RN may also be needed to properly terminate RSYNC line. |
