Pin Function
Supply (Input): +3V to +5V supply.
Ground: Power return.
Output: Charge pump output. Connect to load.
Not internally connected.
Enable (Input): CMOS compatible input. EN high (V_EN = V_IN) enables the
charge pump . EN low (V_IN = 0V) disables the charge pump.

Typicals values at T_A = 25°C. Minimum and maximum values at –40°C ≤ T_A ≤ +85°C.
Turn-on time is the time between V_EN = 0.5 × V_IN and V_OUT = 0.9 (V_OUTmax – V_OUTmin) for a rising EN input.
Turn-off time is the time between V_EN = 0.5 × V_IN and V_OUT = V_IN – 1.9V for a falling EN input.
