LT1934ES6#TRMPBF from Analog Devices, in a TSOT-23-6. 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 | BOOST | power_in | The BOOST pin provides a drive voltage higher than the input voltage to the internal NPN power switch, with the boost capacitor needing at least the minimum boost voltage across it for full switch saturation; BOOST is rated to 40V and must not exceed 20V above the SW pin. |
| 2 | GND | power_in | The GND pin must be tied to a local ground plane below the LT1934 and the circuit components, and the feedback divider returns to this pin. |
| 3 | FB | input | The FB pin is regulated to 1.25V and connects to the feedback resistor divider tap, with VOUT = 1.25V × (1 + R1/R2), and its absolute maximum voltage is 6V. |
| 4 | SHDN | input | The SHDN pin shuts down the LT1934 when tied to ground, requires 2.3V or more for normal operation, is rated to 34V, and should be tied to VIN if shutdown is not used. |
| 5 | VIN | power_in | The VIN pin supplies current to the internal regulator and the internal power switch over the 3.2V to 34V input range and must be locally bypassed. |
| 6 | SW | output | The SW pin is the output of the internal power switch, connects to the inductor, catch diode and boost capacitor, and its voltage is limited to VIN. |
