LM5022MM 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 to the startup regulator, operates from 6 V to 60 V. |
| 2 | FB | input | Feedback pin inverting input to the internal voltage error amplifier with 1.25-V reference. |
| 3 | COMP | bidirectional | Error amplifier output and PWM comparator input with control loop compensation components connected between this pin and the FB pin. |
| 4 | VCC | power_out | Output of the internal high-voltage linear regulator that must be bypassed to GND with a ceramic capacitor. |
| 5 | OUT | output | Output of MOSFET gate driver with 1-A peak current capability connected to the gate of the external MOSFET. |
| 6 | GND | power_in | System ground. |
| 7 | UVLO | input | Input undervoltage lockout connected to input voltage through resistor divider with 20-µA current source providing hysteresis. |
| 8 | CS | input | Current sense input for the switch current used for current mode control and current limiting. |
| 9 | RT/SYNC | input | Oscillator frequency adjust pin and synchronization input where external resistor to GND sets frequency or AC-coupled input accepts external clock synchronization. |
| 10 | SS | input | Soft-start pin with external capacitor to ground charged by 10-µA current source creating ramp voltage for regulator startup. |
