L4984DTR from STMicroelectronics, in a SSOP-10-150mil. 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 | INV | input | Inverting input of error amplifier with 2.5 V reference voltage for PFC output voltage feedback control. |
| 2 | COMP | output | Error amplifier output for voltage loop compensation with internal clamp at 2.4 V to enable burst-mode operation. |
| 3 | MULT | input | Sinusoidal reference input to multiplier for line-current shaping, operating range 0-3 V with internal clamp at 9.5 V. |
| 4 | CS | input | PWM comparator input for MOSFET drain current sensing with 220 ns digital leading-edge blanking and 1.7 V saturation detection for boost inductor protection. |
| 5 | VFF | input | Voltage feedforward input for 1/V2 line-voltage compensation with external RC network (RFF 100 kΩ-2 MΩ, CFF capacitor) and brownout detection below 0.8 V. |
| 6 | PFC_OK | input | Output voltage overvoltage protection monitor with threshold at 2.5 V, feedback failure detection when VPFC_OK > 2.5 V and VINV < 1.66 V, and disable function at 0.23 V. |
| 7 | TIMER | output | Timing capacitor node charged by 142-163 µA internal current source during MOSFET off-time to generate frequency-set ramp. |
| 8 | GND | power_in | Ground return for signal circuits and gate driver with separate PCB trace routing from sense resistor to prevent coupling with bias network grounds. |
| 9 | GD | tri_state | Totem pole gate driver output capable of 600 mA source current and 800 mA sink current with high-level output voltage clamped at 12 V. |
| 10 | VCC | power_in | Positive supply voltage (operating range 10.3-22.5 V) for signal and gate driver circuits with internal 22.5 V minimum zener clamp. |
