SX1301

Suosemi · DC-DC Converters · SOT-23-6

SX1301 from Suosemi, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LX output Power switch output. Drain of the internal 16V / 2A / 0.2Ω N-channel power MOSFET; connect to the boost inductor and Schottky diode. Keep trace short and wide to reduce EMI.
2 GND power_in IC ground. Should be connected close to CIN and COUT directly to a ground plane.
3 FB input Error amplifier inverting input (feedback). Compared against the internal 0.6V reference. Set output voltage via a resistor divider: VOUT = 0.6V × (1 + R1/R2). Sensitive node; keep away from switching LX node.
4 EN input Enable control (active high). VEN ≥ 0.96V enables the converter; VEN ≤ 0.6V puts the part in shutdown (ICC ≈ 0.1µA). Also sinks 20µA when FB drops below 0.3V for output-disconnect (SCP) applications.
5 VCC power_in IC power supply input. Operating range 2.6V to 5.5V (absolute max 6V). Place CIN close to this pin to filter pulsing input current.
6 OC input Adjustable current limit (floating available). External resistor to GND (10kΩ-100kΩ) programs peak switch current from 2.5A down to 0.5A per IOCP = 48000 / R. Keep trace short; do not add capacitance to this pin.
