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.
VIN 2 PWR Input pin.
GND 3 Ground pin.
VOUT 4, 5 PWR Output pin.
FB 6 I Feedback reference pin. An external resistor divider connected to this pin programs the output voltage.
PG 7 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.
SS/TR 8 I Soft startup and voltage tracking pin. An external capacitor connected to this pin sets the internal reference voltage rising time.
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.
