PIN FUNCTIONS
C1– (Pin 1): First Charge Capacitor Negative Input. Connect
a 0.47µF capacitor (C1) between C1+ and C1–.
C1+ (Pin 2): First Charge Capacitor Positive Input. Connect
a 0.47µF capacitor (C1) between C1+ and C1–.
C2– (Pin 3): Second Charge Capacitor Negative Input.
Connect a 0.47µF capacitor (C2) between C2+ and C2–.
C2+ (Pin 4): Second Charge Capacitor Positive Input.
Connect a 0.47µF capacitor (C2) between C2+ and C2–.
VCC (Pin 5): Positive Supply Input. 4.75V ≤ VCC ≤ 5.5V.
Requires a 10µF bypass capacitor to ground (C4).
VOUT (Pin 6): 12V Output. Requires a 10µF or a higher
value bypass capacitor to ground (C3). VOUT = VCC when
in the shutdown mode.
GND (Pin 7): Ground.
SHDN (Pin 8): Active-High TTL Logic Level Shutdown Pin.
SHDN is internally pulled up to VCC. Connect to GND for
normal operation. In shutdown mode, the charge pump is
turned off and VOUT = VCC.
