Pin Functions

PIN I/O DESCRIPTION
NAME NO.
AGND 1 I Signal ground of the IC
FB 2 I Voltage feedback of adjustable output voltage
VOUT 3,4 PWR Boost converter output
EN 5 I Enable logic input. Logic high voltage enables the device. Logic low voltage disables the device and turns it into shutdown mode.
SW 6,7 PWR The switch pin of the converter. It is connected to the drains of the internal power MOSFETs.
VIN 8 I IC power supply input
PGND 9 PWR Power ground
