FUNCTION
NO CONNECT: This pin must be soldered to PCB but not electrically connected to any other
pin or to any external signal, voltage, or ground. This pin may be connected internally. Failure
to follow this guideline may result in device damage.
This is the external feedback input pin. A resistor divider connects from the output to AGND.
The mid-point of the resistor divider is connected to VFB. A feed-forward capacitor is
required parallel to the upper feedback resistor (R
on the VFB node voltage equal to 0.600V.
The quiet ground for the control circuits. Connect to the ground plane with a via right next to
the pin.
Analog input voltage for the control circuits. Connect this pin to the input power supply (PVIN)
at a quiet point. Decouple with a 1uF capacitor to AGND.
POK is an open drain output. Refer to Power OK section for details.
Input Enable. A logic high level on this pin enables the output and initiates a soft start. A logic
low signal disables the output and discharges the output to GND. This pin must not be left
floating.
Input power supply. Connect to input power supply and place input filter capacitor(s) between
these pins and PGND pins 2 to 3.
Not a perimeter pin. Device thermal pad to be connected to the system GND plane for heat-
sinking purposes. See Layout Recommendation section.
