EG1164 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 | REF3.3V | output | 3.3V reference output (3.1V to 3.3V, typical 3.2V) that can source up to 50mA, and should be bypassed with a 0.1uF ceramic capacitor placed close to the pin. |
| 2 | EN | input | Enable pin with a 1.2V comparison threshold (1.15V to 1.25V); when it is below 1.2V the chip enters standby and turns off the 3.3V output, and its start and stop voltages are set by external resistors. |
| 3 | SD | input | High level disables the PWM output cycle by cycle (requires at least 3V), and low level allows PWM output. |
| 4 | SS | input | Soft-start pin where an external capacitor sets the soft-start time through the rate at which its voltage rises. |
| 5 | VSS | power_in | Analog signal ground of the chip. |
| 6 | CP | input | External timing capacitor that sets the PWM frequency as f = 18x10^6 / Cp (Cp in pF), so Cp = 270pF gives about 67kHz, with the chip's operating frequency range stated as 0 to 300kHz. |
| 7 | ERRO | output | Output of the voltage-loop error amplifier. |
| 8 | FB | input | Inverting input of the voltage-loop error amplifier, with a 1.2V reference (1.18V to 1.22V), where the output voltage is set by Vout = (1 + R1/R2) x 1.2V using the external divider. |
| 9 | SDLIN | input | Low-side MOSFET current comparator input, with a 180mV current-limit threshold relative to COM. |
| 10 | LO | output | Drives the low-side power MOSFET on and off, with output limits of -0.3V to VCC+0.3V, source current at least 1.2A and sink current at least 1.5A (pulse width up to 10us). |
| 11 | COM | power_in | Power ground of the chip, used as the return for the power MOSFET drive. |
| 12 | VCC | power_in | Chip supply pin with an operating range of 4V to 20V, with UVLO turn-on at 3.65V and turn-off at 3.6V. |
| 13 | SDHIN | input | High-side MOSFET current comparator input, with a 180mV current-limit threshold relative to VS. |
| 14 | VS | power_in | High-side floating ground, with an absolute range of VB-20V to VB+0.3V. |
| 15 | VB | power_in | High-side floating supply with an absolute maximum of 600V, and a minimum operating voltage of 4V. |
| 16 | HO | output | Drives the high-side power MOSFET on and off, with output limits of VS-0.3V to VB+0.3V, source current at least 1.2A and sink current at least 1.5A (pulse width up to 10us). |
