The LM76005-Q1 only requires a few external components to convert from a wide range of supply voltages to output voltage, as shown in Figure 8-1:

Figure 8-1 LM76005-Q1 Basic Schematic

The LM76005-Q1 also integrates a full list of features to aid system design requirements, such as the following:

• VCC UVLO
• Programmable soft start
• Start-up tracking
• Programmable switching frequency
• Clock synchronization
• Power-good indication

Each system can select the features needed in a specific application. A comprehensive schematic with all features utilized is shown in Figure 8-2:

The external components must fulfill the requirements of the application, but also the stability criteria of the device control loop. The LM76005-Q1 is optimized to work within a range of external components. Inductance and capacitance of the LC output filter each create poles that have to be considered in the control of the converter. For V_OUT = 1 V, 3.3 V, 5V, the recommended output capacitors have been generated assuming typical derating for 16-V, X7R, automotive grade capacitors. For V_OUT = 12 V, the recommended output capacitors have been generated assuming typical derating for 25-V, X7R, automotive grade capacitors, and for V_OUT = 24 V, the recommended output capacitors have been generated assuming typical derating for 50-V, X7R, automotive grade capacitors. If lower voltage, nonautomotive grade, or lower temperature rated capacitors are used, more capacitors than listed are likely to be needed.Table 8-1 can be used to simplify the output filter component selection.
