6 Pin Configuration and Functions

Figure 6-1 9-Pin VQFNRWY Package(Top View)
Table 6-1 Pin Functions
PIN I/O DESCRIPTION
NAME NO.
EN 8 I This is the enable pin of the device. Connect to logic low to disable the device. Pull high to enable the device. Do not leave this pin unconnected.
FB 5 I Voltage feedback input. Connect the resistive output voltage divider to this pin.
GND 4 Ground pin
MODE/SYNC 1 I The device runs in PFM/PWM mode when this pin is pulled low. When the pin is pulled high, the device runs in forced PWM mode. Do not leave this pin unconnected. The mode pin can also be used to synchronize the device to an external frequency. See the Electrical Characteristics for the detailed specification for the digital signal applied to this pin for external synchronization.
COMP/FSET 7 I Device compensation and frequency set input. A resistor from this pin to GND defines the compensation of the control loop as well as the switching frequency if not externally synchronized.
PG 9 O Open-drain power-good output
SS/TR 6 I Soft-start / tracking pin. An external capacitor connected from this pin to GND defines the rise time for the internal reference voltage. The pin can also be used as an input for tracking and sequencing. See Section 10.
SW 3 O This is the switch pin of the converter and is connected to the internal power MOSFETs.
VIN 2 Power supply input. Make sure the input capacitor is connected as close as possible between the VIN pin and PGND.
