Everanalog IC design · DC-DC Converters · SOT-23-6
EA9203 from Everanalog IC design, in a SOT-23-6. 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 | BST | output | High side gate drive boost pin that requires a 0.1μF-1μF capacitor connection to LX to fully turn on the internal high-side NMOS. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Voltage feedback input pin for feedback voltage regulation at 0.8V±1% via resistive divider from VOUT. |
| 4 | SHDN | input | Enable input pin (pull high to enable, pull low to disable) with 100kΩ resistor connection to VIN for auto start-up. |
| 5 | VIN | power_in | Power supply input pin for 4.5V to 24V operation; input capacitors should be placed as close as possible to minimize noise. |
| 6 | LX | output | Power switching node that connects to external inductor for energy storage and output ripple filtering. |
