5 / 20 page ADP1611 Rev. 0 | Page 5 of 20 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS COMP 1 FB 2 SD 3 GND 4 SS 8 RT 7 IN 6 SW 5 ADP1611 TOP VIEW (Not to Scale) Figure 3. Pin Configuration Table 3. Pin Function Descriptions Pin No. Mnemonic Description 1 COMP Compensation Input. Connect a series resistor-capacitor network from COMP to GND to compensate the regulator. 2 FB Output Voltage Feedback Input. Connect a resistive voltage divider from the output voltage to FB to set the regulator output voltage. 3 SD Shutdown Input. Drive SD low to shut down the regulator; drive SD high to turn it on. 4 GND Ground. 5 SW Switching Output. Connect the power inductor from the input voltage to SW and connect the external rectifier from SW to the output voltage to complete the step-up converter. 6 IN Main Power Supply Input. IN powers the ADP1611 internal circuitry. Connect IN to the input source voltage. Bypass IN to GND with a 10 µF or greater capacitor as close to the ADP1611 as possible. 7 RT Frequency Setting Input. RT controls the switching frequency. Connect RT to GND to program the oscillator to 700 kHz, or connect RT to IN to program it to 1.2 MHz. 8 SS Soft-Start Timing Capacitor Input. A capacitor from SS to GND brings up the output slowly at power-up. |
