ETA2822E8A
etasolution · DC-DC Converters · SOP-8-EP
ETA2822E8A from etasolution, in a SOP-8-EP. 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 | SW | output | Inductor connection: connect an inductor between SW and the regulator output, with SW voltage limited to -0.3V to VIN+0.3V per the absolute maximum ratings. |
| 2 | ROSC | passive | Frequency setting: connect a resistor from this pin to GND to set the switching frequency, which the datasheet states can be programmed from 100 kHz to 2 MHz. |
| 3 | RCOMP | passive | Cable resistance compensation adjust: connect a resistor from this pin to GND to compensate for the voltage drop due to cord resistance. |
| 4 | FB | input | Feedback input: connect an external resistor divider from the output to FB and GND to set VOUT, with FB voltage of 0.776 V to 0.824 V (0.800 V typical). |
| 5 | ILIM | passive | Current limit setting: connect a resistor from this pin to GND to set the output current limit value. |
| 6 | BST | passive | Bootstrap pin: connect a 100nF capacitor from this pin to SW, with BST voltage limited to -0.3V to SW+6V per the absolute maximum ratings. |
| 7 | VIN | power_in | Supply voltage: bypass with a 10µF ceramic capacitor to GND; the input operating range is 4V to 36V, with a 42V standoff voltage. |
| 8 | EN | input | Enable pin: drive high to enable the part and low to disable it, with EN voltage limited to -0.3V to VIN+0.3V per the absolute maximum ratings. |
| 9 | GND | power_in | Ground connection on the exposed pad of the ESOP-8 package, which the datasheet lists as pin 9. |
