NAME
V CC
PWRGD
FB1
ILIM1
FUNCTION
Internal Analog Supply. V CC regulates to 1.5V below V VL. Connect a 1μF ceramic capacitor from V CC to GND.
When using a 4.5V to 5.5V supply, connect a 10 Ω resistor from V CC to IN. V CC is used to power the IC’s
internal circuitry.
Open-Drain Power-Good Output. PWRGD is high impedance when controllers 1 and 2 (using the internal
reference) are in regulation. PWRGD is low if the outputs are out of regulation, if there is a fault condition, or if
the IC is shut down. PWRGD does not reflect the status of output 2 in the MAX8664A or when REFIN2 is
connected to an external reference in the MAX8664B.
Feedback Input for Controller 1. Connect FB1 to the center of a resistor-divider connected between the output
of controller 1 and GND to set the desired output voltage. V FB1 regulates to 0.6V.
Current-Limit Set for Controller 1. Connect a resistor from the drain of the high-side MOSFET(s) to ILIM1. See
the Setting the Overcurrent Threshold section.
