Power-Good (PGOOD)
The MAX1510/MAX17510 provide an open-drain
PGOOD output that goes high 2ms (typ) after the out-
put initially reaches regulation during startup as shown
in Figure 3. PGOOD transitions low 10μs after the out-
put goes out of regulation by ± 150mV, or when the

PGOOD to V CC for a logic-level output. Use a 100k Ω
resistor to minimize current consumption.

Applications Information
Dynamic Output-Voltage Transitions
By changing the voltage at REFIN, the MAX1510/
MAX17510 can be used in applications that require
dynamic output-voltage changes between two set

REFIN
points (graphics processors). Figure 4 shows a dynam-
ically adjustable resistive voltage-divider network at
REFIN. Using an external signal MOSFET, a resistor

can be switched in and out of the REFIN resistor-
divider, changing the voltage at REFIN. The two output

voltages are determined by the following equations:
V OUT(LOW) = V REF
