LM5022MME 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 input to the startup regulator, operating from 6 V to 60 V. |
| 2 | FB | input | Inverting input to the internal voltage error amplifier, whose noninverting input connects to a 1.25-V reference. |
| 3 | COMP | bidirectional | Error amplifier output and PWM comparator input, with control loop compensation components connected between this pin and FB. |
| 4 | VCC | power_in | Output of the internal high-voltage linear regulator that must be bypassed to GND with a ceramic capacitor. |
| 5 | OUT | output | MOSFET gate driver output that connects to the external MOSFET gate and provides 1-A peak drive current capability. |
| 6 | GND | power_in | System ground. |
| 7 | UVLO | input | Input undervoltage lockout that sets start-up and shutdown levels through a resistor divider from the input voltage, with a 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 where an external resistor to GND sets the switching frequency, and which can also accept an AC-coupled synchronization clock. |
| 10 | SS | input | Soft-start pin where an external capacitor to ground is charged by a 10-µA current source to create a ramp controlling start-up. |
