Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
EN C1 I Enable logic input. Logic high voltage enables the device. Logic low voltage disables the device and turns it into shutdown mode.
FB B1 I Voltage feedback of adjustable output voltage. Connect to the center tap of a resistor divider to program the output voltage. When it is connected to the VIN pin, the output voltage is set to 12 V by an internal feedback.
GND A2 PWR Ground
SW B2 PWR The switch pin of the converter. It is connected to the drain of the internal power MOSFET.
VIN A1 I IC power supply input
VOUT C2 PWR Output of the boost converter
