LM5030MMX from Texas Instruments, in a VSSOP-10-0.5mm. 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 | VIN | power_in | Source input voltage for start-up regulator, operating range 14 to 100 V. |
| 2 | VFB | input | Inverting input to error amplifier; non-inverting input internally connected to 1.25-V reference. |
| 3 | COMP | output | Error amplifier output with internal 5-kΩ pullup resistor and active sink. |
| 4 | VCC | power_out | Internal high-voltage series pass regulator output with 7.7-V regulation setpoint. |
| 5 | OUT1 | output | PWM controller alternating output for gate driver. |
| 6 | OUT2 | output | PWM controller alternating output for gate driver. |
| 7 | GND | power_in | Return ground. |
| 8 | CS | input | Current sense input; cycle-by-cycle current limit triggered above 0.5 V, disabled if exceeds 0.625 V. |
| 9 | RT | input | Oscillator timing resistor input and external synchronization input. |
| 10 | SS | input | Soft start and shutdown pin with 10-µA current source input; shutdown threshold 0.45 V. |
