PGND
Power ground. Connect all power grounds to this pin.
SGND
Analog ground. SGND and PGND should only have one
point connection.
FB
Buck regulator output feedback pin. Connect to the output
through voltage divider resistor for adjustable output voltage.
RSI
This input resets the 215ms timer. When the output voltage
is within the power-good window, an internal timer is started
and generates a PG signal 215ms later when RSI is low. A
high RSI resets PG and RSI high to low transition restarts
the internal counter if the output voltage is within the window,
otherwise the counter is reset by the output voltage
condition. Do not leave this pin floating.
Typical Applications
Exposed Pad
The exposed pad must be connected to the PGND pin for
proper electrical performance. The exposed pad must also
be connected to as much as possible for optimal thermal
performance.
