XC9142A36CMR-G

Torex Semicon · DC-DC Converters · SOT-25-5

XC9142A36CMR-G from Torex Semicon, in a SOT-25-5. 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. H (>=0.80V) turns the converter Active; L (<=0.20V) puts the device in Stand-by. Do not leave open. VCE absolute max -0.3 to +7.0V.
2 GND power_in Ground reference; standard voltage for all pins.
3 BAT power_in Power input from battery / boost inductor return. Operating range 0.65V to 6.0V (VBAT abs max -0.3 to +7.0V). Startup voltage <=0.90V (RL=1k).
4 VOUT power_out Regulated boost output and internal VDD source. Programmable 1.8V to 5.5V (this option: 3.6V), delivered through the internal load-disconnect PMOS. Abs max -0.3 to +7.0V.
5 Lx output Switching node to external boost inductor. Internal N-ch driver (RLXN ~0.3 ohm) and P-ch synchronous switch (RLXP ~0.3 ohm at IOUT=200mA). Abs max -0.3 to +7.0V.
