DESCRIPTION
Power Ground Pin. Synchronous rectifier current returns through
this pin.
Internal Ground Pin. Control circuitry returns current to this pin.
External feedback network input connection. Connect a resistor from
FB to ground and from FB to V OUT to control the output voltage.
Regulation point at FB = 0.8V Typical.
Compensation pin for error loop. Connect an R and C in series to
ground to control open loop pole and zero.
Shutdown control input. Tie pin to V IN for normal operation, tie to
ground for shutdown. TTL input threshold.
Connect this pin to V IN .
An external clock signal can be connected to this pin to synchronize
the switching frequency.
Internal supply voltage. Control circuitry is powered from from this
pin. Use an RC filter close to the pin to cut down supply noise.
Supply voltage for the output driver stage. Inductor charging current
passes through this pin.
Inductor switching node. Inductor tied between this pin and the
output capacitor to create regulated output voltage.
