ETA2808E8A from etasolution, in a ESOP-8. 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 the inductor between SW and the regulator output, with the SW pin rated from -0.3V (-3V for 10ns) to VIN+0.3V (49V for 10ns). |
| 2 | IN | power_in | Supply voltage input with a wide operating range of 4.6V to 35V (40V input standoff), to be bypassed with a 22μF ceramic capacitor to GND; absolute maximum is -0.3V to 40V. |
| 3 | EN | input | Enable pin: drive high to enable the IC and low to disable it, with EN logic high threshold rising at 1.3V and logic low threshold falling at 1.1V (absolute maximum -0.3V to VIN+0.3V). |
| 4 | ISET | input | External output current limit setting pin; a resistor from this pin to GND sets the CC current as Icc = 160/RISET(kOhm) A, with RISET between 30K and 300K, and absolute maximum pin voltage of 6V. |
| 5 | FB | input | Feedback input; an external resistor divider from the output to FB and GND sets VOUT against the 0.8V typical reference, with R2 between 10kOhm and 100kOhm, and absolute maximum pin voltage of 6V. |
| 6 | OSC | input | External switching frequency setting pin; a resistor from this pin to GND sets the frequency as Fosc = 20000/Rosc(kOhm) kHz, with Rosc between 15K and 170K, and absolute maximum pin voltage of 6V. |
| 7 | LDO | power_out | Internal circuit power supply pin with a typical 5.3V internal voltage, to be bypassed with a 1μF ceramic capacitor to GND; absolute maximum pin voltage is 6V. |
| 8 | BST | passive | Bootstrap pin; connect a 100nF capacitor from BST to SW, with BST voltage rated from -0.3V to SW+6V. |
| 9 | GND | power_in | Ground pin, provided as the exposed thermal pad on the ESOP8 package, which must be connected to the system ground. |
