The output voltage is set at 1.2V by the selection of the two resistors R FB1 and R FB2 , using resistor values from
Table 1. PWM-only mode operation is selected by connecting the SYNC/PWM pin to the VIN pin. The 100% duty cycle
capability is selected by connecting the MODE pin to the VIN pin. A 10 μ F capacitor is selected for the output, as PSAVE
operation is not required in this application.
