LTC3406ES5#TRPBF from Analog Devices, in a TSOT-23-5. 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 | RUN | input | Run control input: forcing it above 1.5V enables the part and forcing it below 0.3V shuts it down, with supply current under 1µA in shutdown; it must not be left floating. |
| 2 | GND | power_in | Ground pin, to which VIN must be closely decoupled with a 2.2µF or greater ceramic capacitor. |
| 3 | SW | output | Switch node connection to the inductor, tied to the drains of the internal main and synchronous power MOSFET switches; SW voltage is rated from -0.3V to (VIN + 0.3V) and peak SW sink and source current is 1.3A. |
| 4 | VIN | power_in | Main supply pin, which must be closely decoupled to GND (pin 2) with a 2.2µF or greater ceramic capacitor; the input voltage range is 2.5V to 5.5V. |
| 5 | VFB | input | Feedback pin (adjustable LTC3406 version) that receives the feedback voltage from an external resistive divider across the output, regulated to the 0.6V reference. |
