Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node connected to the internal MOSFET switches; inductor is connected between this pin and the output capacitor. |
| 2 | SW | output | Switch node connected to the internal MOSFET switches; inductor is connected between this pin and the output capacitor. |
| 3 | SW | output | Switch node connected to the internal MOSFET switches; inductor is connected between this pin and the output capacitor. |
| 4 | PG | tri_state | Open-drain power good output that signals high impedance when VOUT is ready at nominal regulation and pulls low when VOUT falls below nominal threshold. |
| 5 | FB | input | Voltage feedback input internally pulled down for fixed 5.0-V output version; recommend connecting to AGND for improved thermal performance. |
| 6 | AGND | power_in | Analog ground reference that must be connected directly to the exposed thermal pad and common ground plane. |
| 7 | FSW | input | Switching frequency select input with internal pulldown; low selects ~2.5 MHz, high selects ~1.25 MHz for typical operation. |
| 8 | DEF | input | Output voltage scaling input with internal pulldown; low selects nominal output voltage, high selects nominal output voltage plus 5%. |
| 9 | SS/TR | input | Soft-start and tracking input where external capacitor sets the internal voltage reference rise time and enables voltage tracking and sequencing. |
| 10 | AVIN | power_in | Supply voltage for control circuitry that must be connected to the same source as PVIN. |
| 11 | PVIN | power_in | Supply voltage for power stage switching circuit that must be connected to the same source as AVIN. |
| 12 | PVIN | power_in | Supply voltage for power stage switching circuit that must be connected to the same source as AVIN. |
| 13 | EN | input | Enable input with internal ~400 kΩ pulldown resistor; high enables device operation, low or floating disables device and initiates shutdown mode. |
| 14 | VOS | input | Output voltage sense pin for the control loop feedback that must connect to the actual VOUT at the output capacitor. |
| 15 | PGND | power_in | Power ground reference that must be connected directly to the exposed thermal pad and common ground plane for proper dissipation. |
| 16 | PGND | power_in | Power ground reference that must be connected directly to the exposed thermal pad and common ground plane for proper dissipation. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
