APPLICATION INFORMATION
oscillator synchronization
The UCC38C4x oscillator has the same synchronization characteristics as the original bipolar devices. Thus,
the information in the Application Note U100A
, UC3842/3/4/5 Provides Low-Cost Current-Mode Contro
l, (TI
Literature No. SLUA143) still applies. The application note describes how a small resistor from the timing
capacitor-to-ground can offer an insertion point for synchronization to an external clock, (see Figures 2 and 3).
Figure 2 shows how the UCC38C42 can be synchronized to an external clock source. This allows precise
control of frequency and dead time with a digital pulse train.
