Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
SW 1,2 PWR The switch pin of the converter. It is connected to the drain of the internal Power MOSFETs.
VOUT 3,4 PWR Boost converter output pin.
PG 5 OUT Power Good open drain output. Can be left floating if not used.
SS 6 IN Soft startup pin. A soft startup capacitor connects to this pin to set the soft start time.
FB 7 IN Voltage feedback of adjustable versions. Must be connected to VOUT on fixed output voltage version.
HYS 8 OUT EN hysteresis program pin. See the application section for details. Can be left floating if not used.
EN 9 IN Enable logic input. Logic HIGH enables the device. Logic LOW disables the device and turns it into shutdown mode. This pin must be terminated.
VIN 10 IN Supply voltage pin.
GND 11 PWR Ground pin.
