RSC6120S from REASUNOS, in a SOP-14. 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 | VIN | power_in | High-voltage startup input. Connects to the rectified HV bus (rated 150-600V) and feeds the internal 2mA HV startup current source that charges VCC on power-up. |
| 2 | NC | unconnected | No connect. Leave floating or tie to ground per PCB layout convenience. |
| 3 | VCC | power_in | Signal-side supply input, absolute max −0.3 to 20V, operating range 8-20V. UVLO turn-on ≈15V (VCC_On) and turn-off ≈8.7V (VCC_Off); quiescent current ≈720µA. |
| 4 | NC | unconnected | No connect. Leave floating or tie to ground per PCB layout convenience. |
| 5 | FB | input | Voltage feedback input to the error amplifier / OVP comparator, absolute max −0.3 to 5V. OVP trips at V_FB ≈1.20V (recovers at ≈1.08V). |
| 6 | CS | input | Current-sense input from the resonant tank sense network, absolute max −0.3 to 5V. Feeds the rectifier/EA loop; zero-current detect threshold V_ZCD ≈154mV and cycle-by-cycle OCP threshold V_OCP ≈500mV (480/520mV min/max). |
| 7 | GND | power_in | Signal ground / analog return for the control-side circuitry. |
| 8 | PGND | power_in | Power ground return for the low-side gate driver. Keep the loop from PGND through the low-side MOSFET source back to the bulk cap short. |
| 9 | LO | output | Low-side half-bridge gate-drive output, referenced to PGND. Absolute max −0.3V to VCC+0.3V; ~60ns rise / 35ns fall into 1nF; peak source 550mA / peak sink 1000mA on the RSC6120S. |
| 10 | PVCC | power_in | Power-side supply for the low-side gate driver, absolute max −0.3 to 20V. Typically tied to VCC through a small RC decoupling network. |
| 11 | NC | unconnected | No connect. Leave floating or tie to ground per PCB layout convenience. |
| 12 | HS | power_in | High-side floating return (half-bridge switching node reference). Absolute max HB−20V to HB+0.3V; connects to the source of the high-side MOSFET and the bottom of the bootstrap capacitor. |
| 13 | HO | output | High-side floating gate-drive output referenced to HS. Absolute max HS−0.3V to HB+0.3V; ~30ns rise / 35ns fall into 1nF; peak source 550mA / peak sink 1000mA on the RSC6120S. |
| 14 | HB | power_in | High-side floating bootstrap supply, absolute max −0.3 to 600V (relative to GND). Bootstrap capacitor connects between HB and HS to power the high-side driver. |
