PRODUCTION DATA.
Layout is a critical portion of good power supply design. There are several signal paths that conduct fast changing currents or voltages that can interact with stray inductance or parasitic capacitance to generate noise or degrade performance. See Figure 53 for a PCB layout example.
Boxing in the components in the design of Figure 33, the estimated PCB area is 1.025 in2 (661 mm2). This area does not include test points or connectors. If the area must be reduced, then this can be done by using a two sided assembly, and replacing the 0603 sized passives with a smaller-sized equivalent.
