EG1163S from EG Micro, in a SOP-16. 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 | REF5V | power_out | 5V reference output with a maximum output current of 50mA. |
| 2 | EN | input | Chip enable with a 1.2V comparison threshold; below 1.2V the chip enters standby and turns off the 5V output. |
| 3 | SD | input | High level shuts off the PWM output, low level allows PWM output. |
| 4 | SS | passive | Soft-start pin with an external capacitor whose voltage rise rate sets the soft-start time. |
| 5 | VSS | power_in | Chip signal ground (AGND). |
| 6 | CP | passive | External capacitor sets the oscillator frequency, f=(14.4x10^6)/Cp with Cp in pF. |
| 7 | ERRO | output | Output of the voltage loop error amplifier. |
| 8 | FB | input | Inverting input of the voltage loop error amplifier, with 1.2V reference. |
| 9 | SDLIN | input | Input of the low-side MOSFET current comparator, 180mV threshold relative to COM. |
| 10 | LO | output | Output driving the low-side power MOSFET on and off. |
| 11 | COM | power_in | Chip power ground (PGND). |
| 12 | VCC | power_in | Chip supply, voltage range 10V-20V. |
| 13 | SDHIN | input | Input of the high-side MOSFET current comparator, 180mV threshold relative to VS. |
| 14 | VS | power_in | High-side floating ground. |
| 15 | VB | power_in | High-side floating supply, absolute maximum 600V. |
| 16 | HO | output | Output driving the high-side power MOSFET on and off. |
