FUNCTION
Power Ground. Low-side switch source terminal. Connect PGND and the return terminals of
input and output capacitors to the power ground plane.
Inductor Connection. Connect LX to the switching side of the inductor. LX is high impedance
when the device is in shutdown mode.
Open-Drain Power-Good Output. PGOOD goes low when V FB is below the PGOOD threshold.
VID0 Logic Input. Use VID0 and VID1 to select output voltage.
Input Power Supply. Input supply range is 2.7V to 5.5V. Bypass IN with a minimum 10 F F ceramic
capacitor to PGND. See the Typical Application Circuit.
Internally Connected. Leave unconnected.
Feedback Input. Connect FB to the sense the output voltage.
VID1 Logic Input. Use VID0 and VID1 to select output voltage.
Soft-Start and VID Transition Timing Control. Connect a capacitor from SS to PGND to set the
startup time and the output voltage transition timing. See the Output Voltage Transition Timing
section for details.
Input Power Pin for Control Section. Connect to IN.
Enable Input. EN is a digital input that turns the regulator on and off. Drive EN high to turn on the
regulator. Connect to IN for always-on operation.
Error Amplifier Output. Connect compensation network from COMP to signal ground (SGND).
See the Compensation Design Guidelines section.
