PRODUCTION DATA.
PIN | DESCRIPTION | |
---|---|---|
NAME | NO. | |
GND | 1 | Ground pin Source terminal of low-side power NFET as well as the ground terminal for controller circuit. Connect sensitive VFB to this GND at a single point. |
SW | 2 | Switch node connection between high-side NFET and low-side NFET. |
VIN | 3 | Input voltage supply pin. The drain terminal of high-side power NFET. |
PG | 4 | Power good open drain output |
SS | 5 | Soft-start control. An external capacitor should be connected to GND. |
VFB | 6 | Converter feedback input. Connect to output voltage with feedback resistor divider. |
EN | 7 | Enable input control. Active high and must be pulled up to enable the device. |
VBST | 8 | Supply input for the high-side NFET gate drive circuit. Connect 0.1 µF capacitor between VBST and SW pins. |
