EA9203

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.
