NAME 1 VCC A Internal 3.1-V LDO output. Used as supply to internal control circuits. Connect a high-quality 4.7-µF capacitor from this pin to AGND. 2 CBOOT P Bootstrap capacitor connection for gate drivers. Connect a high quality 470-nF capacitor from this pin to the SW pin. 3 SYNC I Synchronization input to regulator. Used to synchronize the device switching frequency to a system clock. Triggers on rising edge of external clock; frequency must be in the range of 1.9 MHz and 2.3 MHz. 4 PVIN1 P Input supply to regulator. Connect input bypass capacitors directly to this pin and PGND pins. Connect PVIN1 and PVIN2 pins directly together at PCB. 5, 6, 7, 8 PGND1 G Power ground to internal low side MOSFET. These pins must be tied together on the PCB. Connect PGND1 and PGND2 directly together at PCB. Connect to AGND and system ground. 9 SW P Regulator switch node. Connect to power inductor. 10, 11, 12, 13 PGND2 G Power ground to internal low side MOSFET. These pins must be tied together. Connect PGND1 and PGND2 directly together at PCB. Connect to AGND and system ground. 14 PVIN2 P Input supply to regulator. Connect input bypass capacitors directly to this pin and PGND pins. Connect PVIN1 and PVIN2 pins directly together at PCB. 15 AVIN A Analog VIN, Connect to PVIN1 and PVIN2 on PCB. 16 FPWM I Do not float. Mode control input of regulator. High = FPWM, low = Automatic light load mode. 17 NC — No internal connection 18 EN I Enable input to regulator. High = on, Low = off. Can be connected to VIN. Do not float. 19 RESET O Open drain reset output flag. Connect to suitable voltage supply through a current limiting resistor. High = regulator OK, Low = regulator fault. Goes low when EN = low. 20 AGND G Analog ground for regulator and system. All electrical parameters are measured with respect to this pin. Connect to PGND on PCB 21 FB A Feedback input to regulator. Connect to output voltage node for fixed VOUT options. Connect to feedback voltage divider for adjustable option. 22 BIAS P Input to auxiliary bias regulator. Connect to output voltage node. |
