PRODUCTION DATA.
PIN | DESCRIPTION | |
---|---|---|
NO. | NAME | |
1 | FB | Feedback pin. Connect to external resistor divider to set output voltage. |
2 | GND | Signal and power ground pin. Place the bottom resistor of the feedback network as close as possible to this pin. |
3 | SW | Switch node. Connect to the inductor and catch diode. |
4 | VIND | Power input supply. |
5 | VINA | Control circuitry supply voltage. Connect VINA to VIND on PC board. |
6 | EN | Enable control input. Logic high enables operation. Do not allow this pin to float or be greater than VINA + 0.3 V. |
DAP | Die Attach Pad | Connect to system ground for low thermal impedance, but it cannot be used as a primary GND connection. |
