NCP1399AADR2G from onsemi, in a SOIC-16-EP. 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 | HV | power_in | High-voltage startup current source input. Connects to the rectified AC line or bulk capacitor to perform startup current-source and Dynamic Self-Supply functions. Absolute max 600 V. |
| 3 | VBULK/PFCFB | input | Bulk voltage monitoring input. Receives a divided bulk voltage to implement brown-out protection and PFC feedback. Absolute max -0.3 to 5.5 V. |
| 4 | SKIP/REM | input | Skip threshold adjust / off-mode (remote) control input. On the NCP1399AA (Ay) version this pin sets the skip-in threshold via a resistor to ground and activates off-mode/Standby when pulled up by an external auxiliary voltage source. Absolute max -0.3 to 10 V (By) or -0.3 to 5.5 V (Ay). |
| 5 | LLC FB | input | LLC feedback input. Defines the operating frequency based on the load; activates skip mode under light load and (on NCP1399Ay) activates off-mode. Absolute max -0.3 to 5.5 V. |
| 6 | LLC CS | input | LLC current sense input. Reads the divided resonant capacitor voltage to perform on-time modulation, out-of-resonance protection, over-current protection and secondary-side short-circuit protection. Absolute max -5 to 5 V. |
| 7 | OTP/OVP | input | Combined over-temperature and over-voltage protection input on a single pin. Absolute max -0.3 to 5.5 V. |
| 8 | PON/OFF | output | PFC turn-off FB level adjust. Pulls the FB pin below a level at which the PFC front-stage operation is disabled. Absolute max -0.3 to 5.5 V. |
| 9 | PFCMODE | output | PFC and external HV switch control output. Provides supply voltage for the PFC front-stage controller and/or enables the VBULK sensing network HV switch. Absolute max -0.3 to VCC+0.3 V. |
| 10 | VCC | power_in | Controller supply voltage. Accepts up to 20 V; typical turn-on threshold 15.8 V, turn-off 9.5 V. |
| 11 | GND | power_in | Analog ground. Common ground for adjustment components, sensing networks and driver outputs. |
| 12 | MLOWER | output | Low-side driver output. Drives the lower half-bridge MOSFET. Absolute max -0.3 to VCC+0.3 V. |
| 14 | MUPPER | output | High-side (floating) driver output. Drives the upper half-bridge MOSFET, referenced to HB. Absolute max VHB-0.3 to VBOOT+0.3 V. |
| 15 | HB | power_in | Half-bridge (high-side floating return). Connects to the switching node between the two half-bridge MOSFETs. Absolute max VBOOT-20 to VBOOT+0.3 V. |
| 16 | VBOOT | power_in | Bootstrap pin - floating VCC supply for the upper (high-side) driver stage. Absolute max -0.3 to 620 V. |
