PIN | DESCRIPTION | |
---|---|---|
NO. | NAME | |
1 | VDD | Supply voltage to gate drivers and internal circuitry. |
2 | VDD | Supply voltage to gate drivers and internal circuitry. |
3 | PGND | Power ground, needs to be connected to Pin 9 and PCB |
4 | VSW | Voltage switching node – pin connection to the inductor. |
5 | VIN | Input voltage pin. Connect input capacitors close to this pin. |
6 | BOOT_R | Bootstrap capacitor CBOOT connections. Connect a minimum 0.1 µF 16 V X5R, ceramic cap CBOOT from BOOT to BOOT_R pins. The bootstrap capacitor provides the charge to turn on the Control FET. The bootstrap diode is integrated. Boot_R is internally connected to VSW. |
7 | BOOT | |
8 | PWM | Pulse Width modulated tri-state input from external controller. Logic Low sets Control FET gate low and Sync FET gate high. Logic High sets Control FET gate high and Sync FET gate Low. Open or High Z sets both MOSFET gates low if greater than the tri-state shutdown hold-off time (t3HT) |
9 | PGND | Power ground |
