Figure 1. Schematic of the MAX1945 for 1MHz all ceramic capacitor application.
In Figure 1, the output inductor is the largest external component with the footprint of 8.2mm x
8.2mm. However, with the new developments at TOKO and Sumida we expect the inductor size
to be reduced to 7.2mm x 7.2mm, further reducing the regulator footprint size.
Figure 2 shows the output ripple voltage, whose peak-to-peak value is less than 10mV for 1.8V
output, well less than 1%.
