DESCRIPTION
Regulated charge pump output.
Positive terminal to the charge pump flying capacitor C2.
Input supply voltage.
Charge pump mode program pin. When V MODE is greater than 1.25V,
a X1 charge pump is used. Otherwise, charge pump switches to X1.5
mode. A voltage divider shown in the typical application circuit
programs the V IN threshold for charge pump mode switching.
This is the feedback pin for output current or voltage regulation. The
voltage of this pin is compared with an internal 315mV reference.
Enable and PWM dimming control input. Pull this pin low to discon-
nect V OUT from V IN and shutdown the SP6683.V OUT is pulled to
ground in shutdown.
Negative terminal to the charge pump flying capacitor, C4.
Ground reference.
Negative terminal to the charge pump flying capacitor, C2.
Positive terminal to the charge pump flying capacitor C4.
