7 / 28 page XR 77103 7/28 REV1B Pin Configuration Pin Functions Pin Number Pin Name Description 1 VOUT3 Buck 3 output sense pin. 2 COMP3 Compensation pin for Buck 3. Connect a series RC circuit to this pin for compensation. 3 A0 I2C address select pin. A0 is internally pulled HIGH through a 100kΩ pull up resistor. 4 VIN(1) IC supply pin. Connect a capacitor as close as possible to this pin and AGND. 5 GND Ground. 6 VCC Internal supply. Connect a ceramic capacitor from this pin to AGND. VCC tied to VIN for VIN = 5V 7 COMP1 Compensation pin for Buck 1. Connect a series RC circuit to this pin for compensation. 8 VOUT1 Buck 1 output sense pin. 9 BST1 Bootstrap capacitor for Buck 1. Connect a bootstrap capacitor from this pin to LX1. 10 VIN1(1) Input supply for Buck 1. Connect a capacitor as close as possible to this pin and PGND. 11 LX1 Switching node for Buck 1. 12 LX1 Switching node for Buck 1. 13 LX2 Switching node for Buck 2. 14 LX2 Switching node for Buck 2. 15 VIN2(1) Input supply for Buck 2. Connect a capacitor as close as possible to this pin and PGND. 16 BST2 Bootstrap capacitor for Buck 2. Connect a bootstrap capacitor from this pin to LX2. 17 VOUT2 Buck 2 output sense pin. 18 COMP2 Compensation pin for Buck 2. Connect a series RC circuit to this pin for compensation. 19 DGND Digital ground. 20 nWR Write protection input for NVM. The data can be written to NVM when this pin is low. This pin is internally pulled high through 100kΩ pull up resistance. NOTE: 1. VIN, VIN1, VIN2, and VIN3 must be tied together.
