Description
Positive Supply Voltage . This pin must be closely decoupled to PGND with a ≥ 22μF
ceramic capacitor.
Not Connected.
Enable Input . Driving this pin above 1.4V enables the device. Driving this pin below 0.3V
puts the device in shutdown mode. In shutdown mode all functions are disabled, drawing
≤ 1μA supply current.
Note: This pin should not be left floating.
Power-OK Output. Open-drain output with 215ms delay. Connect a 100k Ω pull-up resistor
to V OUT or pin VIN for logic levels. Leave this pin unconnected if the Power-OK feature is
not used.
LOW Signal: Out of regulation
HIGH signal: Within Regulation (after 215ms delay)
Analog Ground.
Reset Input for POK. This input resets the 215ms timer of the POK signal.
As long as RSI is low the POK signal will work as described above.
A high input to RSI will reset the 215ms POK timer and delay the signal as long as RSI
stays high. A RSI low-to-high transition restarts the 215ms counter as long as the output
voltage is within regulation.
Note: Do not leave this pin floating.
Feedback Pin . Feedback input to the gm error amplifier. Connect a resistor divider tap to
this pin. The output can be adjusted from 0.6V to 5.25V by V OUT = 0.6V[1+(R1/R2)].
If the fixed output voltage version is used, connect this pin to V OUT .
Analog Ground. GND and PGND should only have one point connection.
Power-Ground. Connect all power grounds to this pin.
Switch Node Connection to Inductor. This pin connects to the drains of the internal main
and synchronous power MOSFET switches.
Exposed Pad. The exposed pad must be connected to PGND. Ensure a good connection
to the PCB to achieve optimal thermal performance.
