output of the regulator via resistor divider to set the output voltage and
provide feedback to the error amplifier
External reference voltage, can be used for margining operation. A
100nF capacitor should be connected between this pin and Gnd.
Output of error amplifier. An external resistor and capacitor network is
typically connected from this pin to Fb to provide loop compensation
Signal ground for internal reference and control circuitry
Use an external resistor from this pin to Gnd to set the switching
frequency
Current limit set point. A resistor from this pin to SW pin will set the
current limit threshold
Power Good status pin. Output is open drain. Connect a pull up resistor
from this pin to Vcc
External Synchronization, this pin is used to synchronize the device’s
switching with an external clock. It is recommended that the external
Sync clock be set to 20% above the free-running frequency. If not used,
this pin can be left floating.
Input voltage for Internal LDO. A 1.0μF capacitor should be connected
between this pin and PGnd. If external supply is connected to
Vcc/LDO_out pin, this pin should be left floating.
Input Bias Voltage, output of internal LDO. Place a minimum 2.2μF cap
from this pin to PGnd
Power Ground. This pin serves as a separated ground for the MOSFET
drivers and should be connected to the system’s power ground plane.
Switch node. This pin is connected to the output inductor
Input voltage for power stage
Supply voltage for high side driver, a 100nF capacitor should be
connected between this pin and SW pin.
Enable pin to turn on and off the device, if this pin is connected to PVin
pin through a resistor divider, input voltage UVLO can be implemented.
Input to error amplifier for tracking purposes
Signal ground for internal reference and control circuitry
