6 / 25 page ![]() Pin configuration STOD13AS 6/25 Doc ID 022733 Rev 1 2 Pin configuration Figure 3. Pin configuration (top view) Table 3. Pin description Pin name Pin n° Description Lx1 1 Boost converter switching node PGND 2 Power ground pin VMID 3 Boost converter output voltage FD 4 Fast discharge control pin. When pulled LOW, the fast discharge after shutdown is active. When pulled HIGH, the fast discharge is OFF AGND 5 Signal ground pin. This pin must be connected to the power ground layer VREF 6 Voltage reference output. 1 µF bypass capacitor must be connected between this pin and AGND SWIRE 7 Negative voltage setting pin EN 8 Enable control pin. High = converter on; Low = converter in shutdown mode VO2 9 Inverting converter output voltage Lx2 10 Inverting converter switching node VIN A 11 Analogic input supply voltage VIN P 12 Power input supply voltage Exposed pad Internally connected to AGND. Exposed pad must be connected to ground layers in the PCB layout in order to guarantee proper operation of the device |
