Power-Good (PGOOD)
The MAX1510 provides an open-drain PGOOD output
that goes high 2ms (typ) after the output initially reach-
es regulation during startup. PGOOD transitions low
10μs after the output goes out of regulation by
±
150mV,
or when the device enters shutdown. Connect a pullup
resistor from PGOOD to V
CC
for a logic-level output.
Use a 100k
resistor to minimize current consumption.
Applications Information
Dynamic Output-Voltage Transitions
By changing the voltage at REFIN, the MAX1510 can
be used in applications that require dynamic output-
voltage changes between two set points (graphics
processors). Figure 4 shows a dynamically 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 volt-
age at REFIN. The two output voltages are determined
by the following equations:
