STMicroelectronics · DC-DC Converters · DFN-8-EP(4x4)
ST8R00WPUR from STMicroelectronics, in a DFN-8-EP(4x4). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | LX | output | Switching output of the step-up converter, with absolute maximum LX pin voltage of 16 V and LX current internally limited. |
| 2 | PGND | power_in | Power ground for the switching stage. |
| 3 | GND | power_in | Analog ground; the exposed pad must be connected to this GND. |
| 4 | IN | power_in | Power input for the analog circuit, with an input voltage range of 4 to 6 V and an absolute maximum of 6 V. |
| 5 | FB | input | Feedback input for the output voltage divider, where the feedback voltage is 1.195 to 1.245 V (1.22 V typ.) at IO = 50 mA. |
| 6 | INH | input | Inhibit input: a voltage above 2 V turns the device ON and a voltage below 0.8 V turns it OFF, with no current flow to the load; absolute maximum inhibit voltage is 6 V. |
| 7 | HV | passive | Trimming pin that must be left floating or connected to GND. |
| 8 | OUT | power_out | Output voltage pin, adjustable from 6 V to 12 V, with an absolute maximum output voltage of 16 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
