PowTech CR PowTech Shanghai · DC-DC Converters · SOT-23-6

PT1301D23F from PowTech CR PowTech Shanghai, 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 CE input Chip enable input. Drive high (>1.2 V typ) to enable normal switching operation; drive low (<0.4 V) to place the device in zero-current shutdown. Typical CE trigger level is 0.8 V with VDD = 3.3 V.
2 EXT output Gate/base drive output for an external power transistor (NMOS or NPN) used to extend output current beyond the internal switch capability. Maximum drive current is 200 mA; on-resistance is 4.4 Ω (EXT-to-VDD) and 2.45 Ω (EXT-to-GND) typ at VDD = 3.3 V.
3 GND power_in Device ground return. Connect to the system ground plane with a short, wide trace.
4 LX output Switching node driven by the internal NMOS power switch. Connect to the junction of the boost inductor and the rectifier diode. Absolute max VLX = 7 V; on-resistance to GND is 0.3 Ω typ; current limit is 1.5 A typ (peak inductor current rating 2.5 A).
5 VDD power_in IC supply input, sensed at the boosted output rail (bootstrapped operation). Operating range 2 V to 6 V; absolute max 7 V. Bypass to GND with a 1 µF MLCC using short, wide traces.
6 FB input Feedback input to the internal error amplifier. Reference voltage is 1.25 V typ (1.225-1.275 V). Set output voltage with a resistor divider from VOUT to GND using Vout = (1 + R1/R2) × 1.25 V; keep node copper small and away from noise sources.
