SLM2169 from SOLA IC, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FB | input | Output voltage feedback pin. Tied to the midpoint of the external RFB1/RFB2 divider from VOUT; internal error amplifier regulates this node to VFB = 0.6 V (±2%). VOUT = 0.6 V × (RFB1 + RFB2) / RFB2. Input current ±0.1 µA max. |
| 2 | VDD | power_in | Power supply pin. Operating range 1.8 V to 5.5 V; absolute max VSS−0.3 V to VSS+6.0 V. Bypass with a 0.1 µF capacitor placed as close to the IC as possible. |
| 3 | EXT | output | External N-channel power MOSFET gate drive pin. Sourcing capability 30 mA typ (VEXT = VDD−0.4 V); sinking 200 mA typ (VEXT = 0.4 V). Output swings between VSS and VDD at the 1.2 MHz switching frequency. Note: datasheet pin-description table lists this as pin '6', which conflicts with the 5-pin SOT-23-5 package diagram; pin 3 is inferred from the package pinout drawing and typical application circuit. |
| 4 | ON/OFF | input | Chip enable / shutdown pin (active-high). 'H' (≥0.75 V) = power-on / normal operation, 'L' (≤0.3 V) = shutdown (standby, IDD ≤ 1 µA). Do not leave floating; input leakage ±0.1 µA. |
| 5 | GND | power_in | Ground / VSS reference for the IC. Connect to system single-point ground; route input, output, and inductor return currents to this node with a low-impedance path. |
