Pin Functions

PINI/ODESCRIPTION
NAMENO.
EN B2 I This is the enable pin of the device. Connecting this pin to ground forces the device into shutdown mode. Pulling this pin high enables the device. This pin must not be left floating and must be terminated.
GND A1, A2, B1 Ground pin.
VIN C1, C2 I Power supply input.
VOUT A3, B3, C3 O Boost converter output.
