3 / 16 page ADP1110 –3– REV. 0 PIN DESCRIPTION Mnemonic Function ILIM For normal conditions this pin is connected to VIN. When lower current is required, a resistor should be connected between ILIM and VIN. Limiting the switch current to 400 mA is achieved by connecting a 220 Ω resistor. VIN Input Voltage. SW1 Collector Node of Power Transistor. For step- down configuration, connect to VIN. For step- up configuration, connect to an inductor/diode. SW2 Emitter Node of Power Transistor. For step- down configuration, connect to inductor/diode. For step-up configuration, connect to ground. Do not allow this pin to go more than a diode drop below ground. GND Ground. AO Auxiliary Gain (GB) Output. The open collec- tor can sink 300 µA. It can be left open if unused. SET Gain Amplifier Input. The amplifier has posi- tive input connected to SET pin and negative input connected to 220 mV reference. It can be left open if unused. FB/SENSE On the ADP1110 (adjustable) version this pin is connected to the comparator input. On the ADP1110-3.3, ADP1110-5 and ADP1110-12, the pin goes directly to the internal application resistor that set output voltage.

ESD SENSITIVE DEVICE 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 ADP1110 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. 8-Lead SOIC (SO-8) A0 ILIM SW1 GND VIN SW2 FB (SENSE)* SET 1 2 3 4 8 7 6 5 TOP VIEW (Not to Scale) ADP1110 *FIXED VERSIONS TJMAX = 90 o, θ JA = 150 oC/W 8-Lead Plastic DIP (N-8) A0 ILIM SW1 GND VIN SW2 *FIXED VERSIONS FB (SENSE)* SET 1 2 3 4 8 7 6 5 ADP1110 TOP VIEW (Not to Scale) TJMAX = 90 o, θ JA = 130 oC/W PIN CONFIGURATIONS |
