SW 1,2 P Regulator switch node. Connect to power inductor. Connect pins 1 and 2 directly together at the PCB. CBOOT 3 P Bootstrap supply input for gate drivers. Connect a high quality 470 nF capacitor from this pin to SW. VCC 4 O Internal 3.15 V regulator output. Used as supply to internal control circuits. Do not connect to any external loads. Can be used as logic supply for control inputs. Connect a high quality 3.3 µF capacitor from this pin to GND. BIAS 5 P Input to internal voltage regulator. Connect to output voltage point. Do not ground. Connect a high quality 0.1 µF capacitor from this pin to GND. SYNC 6 I Synchronization input to regulator. Used to synchronize the regulator switching frequency to the system clock. When not used connect to GND; do not float. FPWM 7 I Mode control input to regulator. High = forced PWM (FPWM). Low = auto mode; automatic transition between PFM and PWM. Do not float. RESET 8 O Open drain reset output. Connect to suitable voltage supply through a current limiting resistor. High = power OK. Low = fault. RESET will go low when EN = low. FB 9 I Feedback input to regulator. Connect to output voltage sense point for fixed 5 V and 3.3 V output. Connect to feedback divider tap point for ADJ option. Do not float or ground. AGND 10 G Analog ground for regulator and system. All electrical parameters are measured with respect to this pin. Connect to EP and PGND on PCB. EN 11 I Enable input to the regulator. High = ON. Low = OFF. Can be connected directly to VIN. Do not float. VIN 12, 13 P Input supply to the regulator. Connect a high quality bypass capacitor(s) from this pin to PGND. Connect pins 12 and 13 directly together at the PCB. N/C 14 - This pin has no connection to the device. PGND 15, 16 G Power ground to internal low side MOSFET. Connect to AGND and system ground. Connect pins 15 and 16 directly together at the PCB. EP 17 G Exposed die attach paddle. Connect to ground plane for adequate heat sinking and noise reduction. |
