is enabled. As the voltage on SS/EN continues to
increase, the current-limit threshold slowly ramps up,
effectively limiting the input inrush current during
power-up ( Figure 3). The MAX8704 reaches the full cur-
rent limit when the SS/EN voltage exceeds 2V.
When SS/EN is pulled low—either by an external open-
drain output or by the internal power-OK (POK) lockout
signal—the MAX8704 pulls the driver (DRV) low and dis-

Output Voltage and Dual Mode? Feedback
The MAX8704’s Dual-Mode operation allows the selec-
tion of two common preset voltages without requiring
external components. Connect FB to V CC for a fixed
1.5V output, or connect FB to GND for a fixed 1.2V out-
put. Alternatively, the output voltage can be adjusted
using a resistive voltage-divider ( Figure 2). The adjust-
ed output voltage is:
V OUT = V FB ? 1 +
R 2 ?
charges the output through a 10 ? discharge FET.
Drive SS/EN with a push/pull output to bypass soft-start.
