8 / 23 page  ADP5138 Data Sheet Rev. A | Page 8 of 23 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 3. Pin Configuration Table 6. Pin Function Descriptions Pin No. Mnemonic Description 1 PVIN1 Power Input for Channel 1. Connect PVIN1 to the input power source, and connect a bypass capacitor between this pin and PGND1. 2 SW1 Switch Node for Channel 1. 3 PGND1 Power Ground for Channel 1. 4 PGND2 Power Ground for Channel 2. 5 SW2 Switch Node for Channel 2. 6 PVIN2 Power Input for Channel 2. Connect PVIN2 to the input power source, and connect a bypass capacitor between this pin and PGND2. 7 FB2 Feedback Voltage Sense Input for Channel 2. Connect this pin to a resistor divider from VOUT2 for the adjustable version. For the fixed output version, connect this pin to VOUT2 directly. 8 EN2 Precision Enable Pin for Channel 2. Use an external resistor divider to set the turn-on threshold. To enable Channel 2 automatically, connect the EN2 pin to PVIN2. 9 POR Power-On Reset Output (Open Drain). 10 PVIN5 Power Input for Channel 5. Connect PVIN5 to the input power source, and connect a bypass capacitor between this pin and ground. 11 FB5 Feedback Voltage Sense Input for Channel 5. Connect this pin to a resistor divider from VOUT5 for the adjustable version. For the fixed output version, connect this pin to VOUT5 directly. 12 VOUT5 Output of Channel 5. Connect a bypass capacitor between this pin and ground. 13 EN5 Precision Enable Pin for Channel 5. Use an external resistor divider to set the turn-on threshold. To enable Channel 5 automatically, connect the EN5 pin to PVIN5. 14 EN3 Precision Enable Pin for Channel 3. Use an external resistor divider to set the turn-on threshold. To enable Channel 3 automatically, connect the EN3 pin to PVIN3. 15 FB3 Feedback Voltage Sense Input for Channel 3. Connect this pin to a resistor divider from VOUT3 for the adjustable version. For the fixed output version, connect this pin to VOUT3 directly. 16 PVIN3 Power Input for Channel 3. Connect PVIN3 to the input power source, and connect a bypass capacitor between this pin and PGND3. 17 SW3 Switch Node for Channel 3. 18 PGND3 Power Ground for Channel 3. 19 PGND4 Power Ground for Channel 4. 20 SW4 Switch Node for Channel 4. 21 PVIN4 Power Input for Channel 4. Connect PVIN4 to the input power source, and connect a bypass capacitor between this pin and PGND4. 22 FB4 Feedback Voltage Sense Input for Channel 4. Connect this pin to a resistor divider from VOUT4 for the adjustable version. For the fixed output version, connect this pin to VOUT4 directly. 23 EN4 Precision Enable Pin for Channel 4. Use an external resistor divider to set the turn-on threshold. To enable Channel 4 automatically, connect the EN4 pin to PVIN4. 1 PVIN1 2 SW1 3 PGND1 4 PGND2 5 SW2 6 PVIN2 7 FB2 17 SW3 18 PGND3 19 PGND4 20 SW4 21 PVIN4 16 PVIN3 15 FB3 ADP5138 TOP VIEW (Not to Scale) NOTES 1. EXPOSED PAD. SOLDER THE EXPOSED PAD TO AN EXTERNAL GROUND PLANE. |
