OCX(欧创芯) · DC-DC Converters · SOT-23-6
OC5864 from OCX(欧创芯), in a SOT-23-6. 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 | NC | unconnected | Not connected (floating) per the datasheet pin definition; leave this pin unconnected. |
| 2 | GND | power_in | Ground reference for the regulator. |
| 3 | FB | input | Output voltage feedback pin; the divider R1/R2 from Vout sets the output, with a 0.812 V typical reference (0.792 to 0.832 V) and an absolute range of -0.3 to 6 V. |
| 4 | EN | input | Chip enable pin with rising threshold 1.35 V and falling threshold 1.17 V, absolute range -0.3 to 6 V; it must not be left floating and should be pulled up to IN (about 510 kΩ) when not under MCU control. |
| 5 | IN | power_in | Chip supply input with a 5.5 to 60 V operating range (absolute maximum -0.3 to 65 V), with UVLO rising at 5.5 V and 500 mV hysteresis. |
| 6 | SW | output | Switching output pin that connects the internal power MOSFET to the inductor and freewheeling Schottky diode; absolute range is -0.3 V to VIN+0.3 V. |
