LT8301ES5#TRMPBF 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 | EN/UVLO | input | Enable/undervoltage lockout pin: pulling it below 0.2V shuts the LT8301 down, its accurate 1.228V threshold can set a VIN UVLO via a resistor divider to ground, and it must be tied directly to VIN if neither function is used. |
| 2 | GND | power_in | Ground reference pin that must be tied directly to the local ground plane. |
| 3 | RFB | input | Input for the external feedback resistor connected to the transformer primary SW pin, whose ratio to the internal 10kΩ resistor and trimmed 1.0V reference sets VOUT, and trace area at this pin should be minimized. |
| 4 | SW | passive | Drain of the 65V internal DMOS power switch, where trace area should be minimized to reduce EMI and voltage spikes. |
| 5 | VIN | power_in | Input supply pin that powers the internal circuitry and serves as the reference for the RFB feedback circuit, and it should be locally bypassed to ground with a capacitor. |
