HT7180SPER from Jiaxing Heroic Elec Tech, in a ESOP-8. 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 | FB | input | Voltage feedback input; the output is set by an external RUP/RDN divider with VREF = 1.204 V, and the pin's absolute maximum range is -0.3 V to 3.6 V. |
| 2 | VOUT | power_in | Power supply pin for the device, with a supply voltage range of 2.7 V to 12.8 V and an absolute maximum of 13 V. |
| 3 | EN | input | Enable logic input: above 1.5 V enables the device, below 0.4 V puts it in shutdown, with an absolute maximum of -0.3 V to 7 V and an internal pull-down of 800 kΩ. |
| 4 | SW | power_out | Switching node of the converter, driving the inductor from the internal 22 mΩ power switch, with an absolute maximum range of -0.3 V to 16 V. |
| 5 | SS/EMI | output | Soft-start programming pin: a Css capacitor to ground sets the soft-start ramp (100 nF typical, 5 µA charging current), and a 330 kΩ resistor in parallel with Css selects the flatter tr/tf mode for better EMI. |
| 6 | ILIM | input | Adjustable switch peak current limit; a resistor connected from this pin to GND sets the limit, which should be set below 10 A. |
| 7 | COMP | output | Output of the internal error amplifier; the loop compensation network (RC, CC, CP) connects between this pin and GND, with an absolute maximum of -0.3 V to 7 V. |
| 8 | VCC | power_out | Output of the internal regulator, which requires a 1 µF ceramic capacitor to ground; absolute maximum -0.3 V to 7 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
