Description
Error Amplifier Output. Connect an RC network from COMP to GND.
Feedback Voltage Sense Input. Connect to a resistor divider from the output voltage, V
Output of the Internal 8 V Regulator. The control circuits are powered from this voltage. Place a 1 µF,
X7R or X5R ceramic capacitor between this pin and GND.
Analog Ground. Return of internal control circuit.
Switch Node Output. Connect to the output inductor.
Power Ground. Return of low-side power MOSFET.
Supply Rail for the High-Side Gate Drive. Place a 0.1 µF, X7R or X5R capacitor between SW and BST.
Power Input. Connect to the input power source and connect a bypass capacitor between this pin and PGND.
Precision Enable Pin. An external resistor divider can be used to set the turn-on threshold. To enable the
part automatically, connect the EN pin to the PVIN pin.
Power-Good Output (Open Drain). A pull-up resistor of 10 kΩ to 100 kΩ is recommended.
Frequency Setting. Connect a resistor between RT and GND to program the switching frequency from
200 kHz to 1.4 MHz.
Synchronization Input. Connect this pin to an external clock to synchronize the switching frequency
within a range from 200 kHz to 1.4 MHz. See the Oscillator section and Synchronization section for
more information.
Soft Start Control. Connect a capacitor from SS to GND to program the soft start time. If this pin is open,
the regulator uses the internal soft start time.
The exposed GND pad must be soldered to a large, external, copper GND plane to reduce thermal
resistance.
The exposed SW pad must be connected to the SW pins of the
else soldered to a large, external, copper SW plane to reduce thermal resistance.
