EG1165 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 | output | 5V reference output that can source up to 10mA, with 4.8-5.0V output when VCC is on (VCC=12V). |
| 2 | EN | input | Chip enable with a 1.2V comparison threshold (1.15-1.25V); when the pin is pulled below 1.2V the chip enters standby and turns off the 5V output. |
| 3 | SD | input | Shutdown input: a high level closes the PWM outputs cycle-by-cycle (3V minimum) and a low level allows PWM output. |
| 4 | SS | input | Soft-start pin for an external capacitor; the capacitor voltage rise rate sets the soft-start time. |
| 5 | VSS | power_in | Analog (signal) ground of the chip, rated absolute maximum range -0.3V to +5.5V on the low-voltage ports referenced to it. |
| 6 | CP | input | External capacitor sets the oscillator frequency over 20Hz-500kHz using f = 11.8×10^6 / CP (CP in pF); the datasheet example gives about 59kHz for 100pF. |
| 7 | ERRO | output | Output of the voltage-loop error amplifier, with source/sink capability of 15-25µA. |
| 8 | FB | input | Inverting input of the voltage-loop error amplifier, with a 1.2V feedback reference (1.188-1.212V) and input bias current of 0.1µA maximum. |
| 9 | SDLIN | input | Low-side MOS current comparator input, with a 180mV current-limit threshold referenced to COM. |
| 10 | LO | output | Drives the low-side power MOSFET on and off; peak source 1.5A minimum and peak sink 2A minimum (pulse width ≤10µs). |
| 11 | COM | power_in | Power ground of the chip, to which the low-side driver and current comparator are referenced. |
| 12 | VCC | power_in | Chip supply input with an operating range of 10V to 20V (absolute maximum -0.3V to 20V); UVLO turn-on about 16V and turn-off about 8V. |
| 13 | SDHIN | input | High-side MOS current comparator input, with a 180mV current-limit threshold referenced to VS. |
| 14 | VS | power_in | High-side floating ground; absolute maximum range is VB-20V to VB+0.3V. |
| 15 | VB | power_in | High-side floating bootstrap supply with an operating range of 10V to 600V. |
| 16 | HO | output | Drives the high-side power MOSFET on and off; referenced to VS, with peak source 1.5A and sink 2A minimum (pulse width ≤10µs). |
