GNDA
Ground A.
MOSFET source, or to sense resistor ground.
Low Side FET Driver for A.
MOSFET for synchronous operation. The trace from this pin to the MOSFET
gate should be <0.5

VCC.
Internal IC supply. Connect to system 12V supply, and decouple with a
0.1
μ
F ceramic capacitor.
Power Good Flag.
An open collector output that will be logic LOW if the
output voltage is not within +11/
–
12% of the nominal output voltage setpoint.
Phase Control.
Connecting this pin to bypass causes a synchronized clock
signal to appear on CLK. Connecting this pin to ground allows the CLK pin to
accept a clock signal for synchronization.
Current Share.
Connecting this pin to the ISHR pin of another FAN5092
enables current sharing.
Droop Control/E*-mode Control.
A resistor from this pin to ground sets the
amount of droop by controlling the gain of the current sense amplifier.
Connecting this pin to bypass turns off Phase A.
Output Enable.
A logic LOW on this pin will disable the output. An internal
current source allows for open collector control. This pin also doubles as soft
start.
Frequency Set.
A resistor from this pin to ground sets the switching
frequency. See Apps section.
Voltage Feedback.
Connect to the desired regulation point at the output of
the converter.
Ground-side current sense pin. Connect directly to low-side
