DESCRIPTION
1
V
OUT
Regulated charge pump output.
2
C1P
Positive terminal to the charge pump flying capacitor C2.
3
V
IN
Input pin for the 2.7V to 5.5V supply voltage.
4
V
MODE
Charge pump mode program pin. When V
MODE
is greater than 1.25V,
X1.5 charge pump is used. Otherwise, charge pump switches to X2
mode. A voltage divider shown in typical application circuit programs
the V
IN
threshold for charge pump mode switching.
5
FB
This is the feedback pin for output current or voltage regulation. The
voltage of this pin is compared with an internal 306mV reference.
6
EN/PWM
Enable and PWM dimming control input. Pull this pin low to discon-
nect V

from V
IN
and shutdown the SP6682.

C2N
Negative terminal to the charge pump flying capacitor, C4.
8
GND
Ground reference.
9
C1N
Negative terminal to the charge pump flying capacitor, C2.
10
C2P
Positive terminal to the charge pump flying capacitor C4.
