3 / 16 page ADP1073 –3– REV. 0 PIN FUNCTION DESCRIPTIONS Pin Mnemonic Function 1ILIM For normal conditions this pin is con- nected to VIN. When a lower current limit is required, a resistor should be connected between ILIM and VIN. Limit- ing the switch current to 400 mA is achieved by connecting a 220 Ω resistor. 2VIN Input Voltage. 3 SW1 Collector Node of Power Transistor. For step-down configuration, connect to VIN; for step-up configuration, connect to an inductor/diode. 4 SW2 Emitter Node of Power Transistor. For step- down configuration, connect to inductor/diode; for step-up configura- tion, connect to ground. Do not allow this pin to drop more than a diode drop below ground. 5 GND Ground. 6 AO Auxiliary Gain (GB) Output. The open collector can sink 100 µA. 7 SET Gain Amplifier Input. The amplifier’s positive input is connected to the SET pin and its negative input is connected to the 212 mV reference. 8 FB/SENSE On the ADP1073 (adjustable) version this pin is connected to the comparator input. On the ADP1073-3.3, ADP1073- 5 and ADP1073-12, the pin goes di- rectly to the internal application resistor that sets 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 ADP1073 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.
