Pin Functions

PIN DESCRIPTION
NAME NO.
SW 1, 2 Switch pin of the power stage.
DEF 3 This pin is used for internal logic and needs to be pulled high. This pin must be connected to the AVIN pin.
PG 4 Power good open drain output. A pull up resistor can not be connected to any voltage higher than the input voltage.
FB 5 Feedback pin, for regulating the output voltage.
AGND 6 Analog ground.
CP 7 Internal charge pump's flying capacitor. Connect a 10nF capacitor between CP and CN.
CN 8 Internal charge pump's flying capacitor. Connect a 10nF capacitor between CP and CN.
SS 9 Soft-start control pin. A capacitor is connected to this pin and sets the soft startup time. Leaving this pin floating sets the minimum start-up time.
AVIN 10 Analog supply input voltage pin.
PVIN 11,12 Power supply input voltage pin.
EN 13 Enable pin. This pin has an active pull down resistor of typically 400kΩ.
PGND 14,15 Power ground.
VOS 16 Output voltage sense pin. This pin must be directly connected to the output voltage.
Thermal Pad The exposed thermal pad must be connected to AGND.
