42 / 47 page  Application examples PM6641 42/47 The default switching frequency has been selected (750 kHz) and the tracking discharge has been enabled in agreement with DDR2 JEDEC specifications. No external resistor dividers are required for these output voltage levels. The allowed inductor current ripple is about 35 % of the expected peak load. The power and signal components have been selected in agreement with Chapter 8: Components selection equations. The following schematic and bill of materials (BOM) are for reference design. Figure 35. Suggested schematic for DDR2 and chipset power supply |
