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).
