Specifications subject to change without notice. PIN FUNCTION DESCRIPTIONS Pin No. Mnemonic Function 1VIN Input Voltage. 2CT External Capacitor Connection. This capacitor sets the operating frequency of the device. The frequency is also dependent on the input voltage level. 3ITH Error Amplifier Decoupling Pin. Pin 3 voltage level causes the comparator current threshold to increase. 4 SENSE(–) This connects to internal resistive divider, which senses the output voltage. Pin 4 is also the (–) input for the current comparator. 5 SENSE(+) This provides the + input to the current comparator. The offset between Pins 4 and 5 together with RSENSE establish the current trip threshold. 6 SHUTDOWN 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. 7 GND 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. 8 P-DRIVE Provides high current drive for the MOSFET. Voltage swing is from VIN to ground at this pin. (–40 C ≤ T A ≤ +85 C 1 , VIN = 10 V, unless otherwise noted) CAUTION 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. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
