6.1.1 LM63460EVM-2MHZ Schematic

Figure 6-1 shows the schematic for the LM63460EVM-2MHZ. Suitable component placements configure the EVM to accommodate the EN/SYNC and RT pin features of the LM63460-Q1. More specifically, C20 (1 nF) connects SYNC from header J3 to the EN/SYNC pin of the LM63460-Q1, and R11 (6.04 kΩ) sets the switching freqeunecy at 2.1 MHz.
