LM5022QDGSRQ1 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 the start-up regulator operating from 6 V to 60 V. |
| 2 | FB | input | Inverting input to the internal voltage error amplifier with non-inverting input connecting to 1.25-V reference. |
| 3 | COMP | output | Error amplifier output and PWM comparator input; control loop compensation components connect between this pin and FB pin. |
| 4 | VCC | power_out | Output of the internal high-voltage linear regulator; bypass to GND pin with ceramic capacitor. |
| 5 | OUT | output | Output of MOSFET gate driver with 1-A peak current capability; connect to external MOSFET gate. |
| 6 | GND | power_in | System ground. |
| 7 | UVLO | input | Undervoltage lockout input; set start-up and shutdown levels via resistor divider with 20-µA hysteresis current source. |
| 8 | CS | input | Current sense input for switch current used in current mode control and current limiting. |
| 9 | RT/SYNC | input | Oscillator frequency adjust pin and external synchronization input; external resistor to GND sets frequency or AC-coupled clock input for synchronization. |
| 10 | SS | input | Soft-start pin; external capacitor to ground charged by 10-µA current source creates ramp voltage for regulator start-up. |
