Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 1 I Enable pin. Pull High to enable the device. Pull Low to disable the device. This pin has an internal pull-down resistor of typically 400 kΩ when the device is disabled.
PG 2 O Power good open drain output pin. A pull-up resistor can be connected to any voltage less than 6V. Leave it open if it is not used.
VIN 3,4 PWR Input voltage pin.
GND 5,6 Ground pin.
FB 7 I Feedback reference pin. An external resistor divider connected to this pin programs the output voltage.
VOUT 8 PWR Output voltage pin.
Exposed Thermal Pad The exposed thermal pad must be connected to the GND pin. Must be soldered to achieve appropriate power dissipation and mechanical reliability.
