| Pin Name | Pin No.
(SOT-23-6) | Pin No.
(SOT-23-5) | Pin Function |
| EN | 1 | 1 | Enable control pin.Pull high to turn the IC on,and pull low to disable the IC.Don't leave
this pin floating. |
| GND | 2 | 2 | Ground pin. |
| LX | 3 | 3 | Power switching node.Connect an inductor to the drains of internal high side PMOS
and low side NMOS. |
| VIN | 4 | 4 | Power supply input pin.Placed input capacitors as close as possible from VIN to GND
to avoid noise influence. |
| PG | 5 | | Open drain power good output pin. |
| FB | 6 | 5 | Voltage feedback input pin.Connect FB and Vour with a resistive voltage divider.This IC
senses feedback voltage via FB and regulates it at 0.6V. |
