TMI2283QE
TMI · DC-DC Converters · SOP-8
TMI2283QE from TMI, in a SOP-8. 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 | FB | input | Feedback pin that senses the output voltage through the resistor divider (1.22V typical feedback voltage) and is also used for output line drop compensation. |
| 2 | FSW | passive | Switching frequency set pin; connect a resistor to ground, and if floating Fs=120kHz (range 120kHz to 380kHz). |
| 3 | ISET | passive | Output current limit set pin; connect a resistor to ground, and if floating the default limit is typically 3.5A at 5V output. |
| 4 | IN | power_in | Power input pin with 4.5V to 30V operating range. |
| 5 | SW | power_out | Switch pin connected to the external inductor. |
| 6 | SW | power_out | Switch pin connected to the external inductor. |
| 7 | GND | power_in | Ground. |
| 8 | GND | power_in | Ground. |
