LT8301IS5#WTRPBF

Analog Devices · DC-DC Converters · TSOT-23-5

LT8301IS5#WTRPBF 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: pull it below 0.2V to shut down the LT8301, it has an accurate 1.228V threshold for programming VIN UVLO with a resistor divider, and it should be tied directly to VIN if neither function is used.
2 GND power_in Ground pin that must be tied directly to the local ground plane.
3 RFB input Input for the external feedback resistor, connected from this pin to the transformer primary SW pin, where the resistor ratio to an internal 10kΩ resistor and a trimmed 1.0V reference sets the output voltage, and trace area at this pin should be minimized.
4 SW output Drain of the internal 65V 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.
