XC9142A50CER-G

Torex Semicon · DC-DC Converters · DFN-6(1.8x2)

XC9142A50CER-G from Torex Semicon, in a DFN-6(1.8x2). 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 BAT power_in Battery / power input pin. Absolute maximum -0.3V to +7.0V. Operating input voltage 0.65V to 6.0V; the internal VDD generator uses VOUT once the converter is running.
2 GND power_in Ground reference. Standard voltage for all other pins.
3 CE input Chip Enable input. CE=H activates the converter, CE=L puts the device into stand-by (and, on A-type, engages complete output disconnect and CL auto-discharge). Do not leave open. Absolute max -0.3V to +7.0V.
4 GND power_in Second ground pin on USP-6C package (also serves as dissipation-pad tie point). The exposed dissipation pad should be tied to the GND (No.2, 4) pin if connected.
5 Lx power_out Switching node. Connects to the external boost inductor. Internal N-channel driver (0.3Ω typ) pulls Lx to GND; internal P-channel synchronous switch (0.3Ω typ) connects Lx to VOUT. Absolute max -0.3V to +7.0V.
6 VOUT power_out Regulated boost output, 5.0V (±2.0%) for the -50 option, up to 500mA at VOUT=5.0V with VBAT=3.3V (typ). Feedback and load-disconnect controller sense this node. Absolute max -0.3V to +7.0V.
