LM5020MMX-1 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 internal start-up regulator with input range of 13V to 100V. |
| 2 | FB | input | Inverting input of the internal error amplifier; non-inverting input internally connected to 1.25V reference. |
| 3 | COMP | output | Open-drain output of the error amplifier for pulse width modulator input with internal 5K pull-up resistor to 5V. |
| 4 | VCC | power_out | Regulated output of the internal high-voltage series pass regulator with 7.7V nominal output voltage. |
| 5 | OUT | output | Gate driver output of the PWM controller with 1A peak current capability for source and sink. |
| 6 | GND | power_in | Ground return connection. |
| 7 | UVLO | input | Line under-voltage shutdown input with 1.25V threshold set by external resistor divider and internal 20µA hysteresis current source. |
| 8 | CS | input | Current sense input for cycle-by-cycle over-current protection; output switches low when CS voltage exceeds 0.5V with 50ns leading edge blanking. |
| 9 | RT/SYNC | input | Oscillator timing resistor pin where external resistor to ground sets frequency; also accepts external clock synchronization pulses above 3.7V peak. |
| 10 | SS | input | Softstart input where external capacitor and internal 10µA current source set the soft-start ramp rate. |
