EA8273T7R

Everanalog IC design · DC-DC Converters · SOT-563

EA8273T7R from Everanalog IC design, in a SOT-563. 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 PWR power_in Power input pin for the regulator, operating from 4.5V to 16V with an absolute maximum of -0.3V to +17V; two 10uF MLCC capacitors are recommended between PWR and GND.
2 SWITCH output Internal MOSFET switching output that must be connected through a low-pass filter to obtain a stable DC output; the absolute maximum SWITCH pin voltage is -1V to +17.5V.
3 GND power_in Ground pin.
4 BOOT power_in Power input for the internal high-side N-MOSFET gate driver; connect a 33nF ceramic capacitor from BOOT to SWITCH, with BOOT voltage limited to VSWITCH-0.3V to VSWITCH+5V.
5 RUN input On/off control input: above 1.2V (typ.) enables the regulator and below 0.4V shuts it down; the absolute maximum rating is -0.3V to +6.3V, and it may be tied to PWR through a 150kΩ resistor for automatic startup but must not be shorted directly to PWR.
6 FBK input Feedback input that connects through a resistor divider between the output and GND to set the output voltage, with a reference of 0.807V typ. (0.791V to 0.823V) and an absolute maximum of -0.3V to +6.3V.
