LT8306RS6#WTRMPBF 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 | SENSE | input | Current-sense comparator input that must be Kelvin-connected to the positive terminal of the current-sense resistor in the bottom MOSFET source, with absolute maximum rating of -0.3V to 0.3V. |
| 2 | GND | power_in | Ground pin that must be tied directly to the ground plane. |
| 3 | GATE | output | Gate drive for the external N-channel MOSFET, swinging from ground to an internal 8V supply; absolute maximum is -0.3V to 10V and no positive or negative voltage source may be applied to this pin. |
| 4 | RFB | input | Input for the external feedback resistor connected to the transformer primary SW node, where the RFB current is limited to -2mA to 200µA and no voltage may be forced on this pin. |
| 5 | VIN | power_in | Input supply for internal circuitry and feedback reference, operating from 4.5V to 60V (absolute maximum -0.3V to 60V) and to be locally bypassed to ground with a ceramic capacitor. |
| 6 | EN/UVLO | input | Enable and undervoltage-lockout pin that shuts down the device when pulled below 0.2V, has an accurate 1.228V enable threshold, and must be tied to VIN if unused (absolute maximum -0.3V to VIN). |
