EG1162 from EG Micro, in a SOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	REF3.3V	power_out	3.3V internal reference output, maximum output current 50mA. Bypass with a small (e.g. 1uF) ceramic capacitor placed close to the pin.
2	EN	input	Chip enable pin. Comparator threshold 1.2V (typ). When EN < 1.2V, the chip enters standby and the 3.3V reference output is disabled. External resistor divider (R20/R21) sets the start/stop voltages.
3	SD	input	Shutdown input. Logic HIGH disables the PWM output; logic LOW enables PWM output. Threshold approximately 3V.
4	SS	input	Soft-start pin. Connect an external capacitor to GND; the capacitor's ramp rate determines the soft-start time.
5	VSS	power_in	Analog signal ground (AGND) for the chip.
6	CP	input	Oscillator timing capacitor pin. External capacitor Cp sets the PWM switching frequency: f = (18 x 10^6) / Cp (Cp in pF). Example: Cp = 270pF → ~67 kHz.
7	ERRO	output	Voltage-loop error amplifier output. Used for external loop compensation. Output current capability typ 20uA (15-25uA).
8	FB	input	Voltage-loop error amplifier inverting (negative) input. Internal reference 1.2V (typ). Set output voltage via divider: Vout = (1 + R1/R2) x 1.2V.
9	SDLIN	input	Low-side MOSFET current-sense comparator input. Trip threshold 180mV relative to COM (PGND). Used for cycle-by-cycle low-side current limit.
10	LO	output	Low-side gate driver output. Controls the turn-on/turn-off of the low-side (synchronous rectifier) power MOSFET. Source/sink capability ~1.8A/2A peak.
11	COM	power_in	Power ground (PGND) return for the low-side driver.
12	VCC	power_in	Low-side chip supply. Operating range 4.5V-20V (absolute max 20V). UVLO thresholds: ON = 4.6V, OFF = 3.8V. Requires a ~10uF storage capacitor to GND.
13	SDHIN	input	High-side MOSFET current-sense comparator input. Trip threshold 180mV relative to VS. Used for cycle-by-cycle high-side (peak) current limit.
14	VS	output	High-side floating ground / switch node reference. Connects to the source of the high-side MOSFET and the bootstrap capacitor's low side. Absolute rating VB-20 to VB+0.3V.
15	VB	power_in	High-side floating (bootstrap) supply. Typical operating range 4V to 600V referenced to VS. Bootstrap capacitor connects between VB and VS.
16	HO	output	High-side floating gate driver output. Controls the turn-on/turn-off of the high-side power MOSFET, swinging between VS and VB. Source/sink capability ~1.8A/2A peak.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`eg1162.step`	217 KB	You want the bare part, or you mark your own boards.
`eg1162-etched.step`	1.8 MB	You want the part with `EG1162` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 458 faces against 267 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
