XC9236A33CMR-G

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

XC9236A33CMR-G from Torex Semicon, in a SOT-25-5. 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 VIN power_in Power input with an operating range of 2.0V to 6.0V for A-type devices and an absolute maximum rating of -0.3V to 6.5V; a bypass capacitor CIN should be placed as close as possible to the VIN and VSS pins.
2 VSS power_in Ground pin that should be shorted to the other VSS pin on the package (the USP variants use pins 2 and 5), and the datasheet gives no separate electrical limit for it.
3 CE/MODE input High-active enable pin: H level is VIN - 0.65V ≤ H ≤ 6.0V and L level is 0V ≤ L ≤ 0.25V for the XC9236 series, and the pin must not be left open.
4 VOUT power_out Fixed output voltage pin for A/B/C/E/G types, which in the A33 device is the 3.3V regulated output, with an absolute maximum rating of -0.3V to 6.5V.
5 Lx output Switching output pin driven by the internal P-channel and N-channel driver transistors, with an absolute maximum voltage of -0.3V to VIN + 0.3V and a pin current limit of ±1500 mA.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin (2) Sn-AG-Cu is used for the package terminals. If eutectic solder is used, mounting reliability is decreased. Please do not use eutectic solder paste. 21
