DESCRIPTION

1

C1-

Negative terminal for the first chargepump capacitor

2

C1+

Positive terminal for the first chargepump capacitor

3

C2-

Negative terminal for the second charge-pump capacitor

4

C2+

Positive terminal for the second charge-pump capacitor

5

Vcc

Supply Voltage

6

Vout

+12V Output Voltage. VOUT = VCC when in shutdown mode.

7

GND

Ground

8

SHDN

Active-high CMOS-logic level Shutdown Input. SHDN is internally pulled up to VCC.

Connect to GND for normal peration. In shutdown mode, the charge pumps are turned

off and VOUT = VCC.

BLOCK DIAGRAM

C3 must be placed as close to the device aspossible and could be

omitted if very low outputnoise performance are not required.
