AN1782 Maxim Integrated Products, AN1782 Datasheet - Page 2

• Manufacturer Part Number: AN1782
• Description: Small Footprint, 10us Response Time, 10mV Output Ripple, 1mhz, 6A Step-down Regulator
• Manufacturer: Maxim Integrated Products

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%.
