# EA2206T5R

**Everanalog IC design** · DC-DC Converters · SOT-23-5

EA2206T5R from Everanalog IC design, in a SOT-23-5. 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 | SWITCH | output | Power switch output pin that connects to the power inductor and output rectifier; the absolute maximum SWITCH pin voltage is -0.3V to +30V and the NMOS leakage is specified at VSWITCH = 20V. |
| 2 | GND | power_in | Ground pin, which the datasheet recommends connecting to a large area ground plane. |
| 3 | FBK | input | Feedback input that connects through voltage-dividing resistors to GND to set the output voltage; the absolute maximum FBK pin voltage is -0.3V to +6V and the reference voltage is 1.206V to 1.254V. |
| 4 | RUN | input | On/off control input that must not be left floating; the datasheet gives an input low voltage of 0.4V and an input high voltage of 1.5V, with an absolute maximum of -0.3V to +6V. |
| 5 | PWR | power_in | Input supply pin with a recommended supply range of 2.5V to 5.5V and an absolute maximum of -0.3V to +6V; a 10uF X5R/X7R MLCC should be placed as close to this pin as possible, referenced to GND. |
