8.1.1 External Components

The procedure for calculating the external components is illustrated with the following design example. The Bill of Materials for this design is listed in Table 1. The circuit shown in Functional Block Diagram is configured for the following specifications:

• V_OUT = 5 V
• V_IN = 7 V to 42 V
• Fs = 300 kHz
• Minimum load current (for CCM) = 100 mA
• Maximum load current = 0.5 A
