Function

VIN  
CT  
Input Voltage.  
External Capacitor Connection. This capacitor sets the operating frequency of the device. The frequency is  
also dependent on the input voltage level.  
3
4
ITH  
Error Amplifier Decoupling Pin. Pin 3 voltage level causes the comparator current threshold to increase.  
SENSE(–)  
This connects to internal resistive divider, which senses the output voltage. Pin 4 is also the (–) input for the  
current comparator.

8
SENSE(+)  
SHUTDOWN  
GND  
This provides the + input to the current comparator. The offset between Pins 4 and 5 together with RSENSE  
establish the current trip threshold.  
When this pin is pulled high, it keeps the MOSFET turned off. When the pin is pulled to ground, the  
ADP1147 functions normally. This pin cannot be left floating.  
Independent ground lines must be connected separately to (a) the negative pin of COUT and (b) the cathode  
of the Schottky diode and the negative terminal of CIN  
.
P-DRIVE  
Provides high current drive for the MOSFET. Voltage swing is from V to ground at this pin.

CAUTIO N  
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily  
accumulate on the human body and test equipment and can discharge without detection.  
Although the ADP1147 features proprietary ESD protection circuitry, permanent damage may  
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD  
precautions are recommended to avoid performance degradation or loss of functionality.
