# XCA201A06BCR

**Torex Semicon** · DC-DC Converters · DFN-6-EP(2x2)

XCA201A06BCR from Torex Semicon, in a DFN-6-EP(2x2). 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 | NC | unconnected | No connection; the datasheet lists this pin as not connected. |
| 2 | CE | input | Chip enable: high (1.5V min) activates the device, low (0.4V max) puts it in standby, and the datasheet says the CE pin must not be left open, with an absolute maximum of 6.0V. |
| 3 | VIN | power_in | Power input with a 2.5V to 5.5V operating range and an absolute maximum rating of -0.3V to 6.0V. |
| 4 | LX | output | Switching output node driving the inductor; the absolute maximum voltage is -0.3V to VIN+0.3V. |
| 5 | GND | power_in | Ground reference; if the dissipation pad needs to be connected to other pins, the datasheet says it should be connected to this GND pin. |
| 6 | FB | input | Output voltage sense input for the external feedback divider, regulated to a 0.6V reference (0.582V to 0.618V). |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
