LM3488MM from Texas Instruments, in a MSOP-8. 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 | ISEN | input | Current sense input pin where voltage across external sense resistor is measured. |
| 2 | COMP | output | Error amplifier output compensation pin where external resistor-capacitor network provides loop compensation. |
| 3 | FB | input | Feedback input pin where output voltage divider is adjusted to provide 1.26V reference for regulation. |
| 4 | AGND | power_in | Analog ground reference pin. |
| 5 | PGND | power_in | Power ground reference pin. |
| 6 | DR | output | Gate drive output pin that drives the gate of the external N-channel MOSFET. |
| 7 | FA/SYNC/SD | input | Frequency adjust/synchronization/shutdown input pin; resistor to ground sets oscillator frequency, external clock synchronizes controller, logic high for ≥30µs initiates shutdown mode drawing <10µA from supply. |
| 8 | VIN | power_in | Power supply input pin with operating range of 2.97V to 40V. |
