Note 3: The dropout voltage is defined as V
Note 4: Dropout voltage (V
Note 5: The maximum output current is guaranteed by correlation to the p-channel current-limit threshold, p-channel on-resistance,
Note 6: Tested at 1.4V default output voltage for the MAX8660, MAX8660A, and MAX8661. Tested at 1.15V default output voltage
Note 7: All output voltages are possible in normal mode. In forced-PWM mode, the minimum output voltage is limited by 0.167 x

The given values assume R
n-channel on-resistance, oscillator frequency, input voltage range, and output voltage range. The maximum output current
in the Electrical Characteristics table is the worst-case output current for the components shown in Figure 3 over then entire
specified range of input and output voltage. More output current may be available when alternate components and voltage
ranges are used. See the Step-Down Converter Output Current section for more information.
