8.2 Typical Application

The application covers the input voltage range from 4.5 V to 14 V at the full 1-A output current. The output capacitors are designed for an output voltage of -1.8 V. With output voltages below -1.8V (larger negative voltages), the output capacitance has to be increased as described in the Detailed Design Procedure. The minimum supply voltage is defined by the 70% duty cycle limit, output current and the output voltage. Please see Figure 36 to Figure 38 for the recommended input voltage levels to generate a specific output voltage.
