3 / 8 page ADP1109 –3– REV. 0 PIN FUNCTION DESCRIPTIONS Pin Mnemonic Function 1VIN Input Supply Voltage. 2, 5, 6 NC No Connection. 3 SW Collector Node of Power Transistor. 4 GND Ground. 7 SHUTDOWN When logic low is applied to this pin, oscillator is shut down. 8 FB(SENSE) On the ADP1109A (Adjustable), this pin goes directly to the comparator input. On the ADP1109-3.3, ADP1109-5 and ADP1109-12, this pin is connected through the internal resistor that sets the output voltage.

Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP1109 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. WARNING!
