LM3488MMX from Texas Instruments, in a VSSOP-8-0.65mm. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ISEN | input | Current sense input pin for voltage generated across external sense resistor (maximum 600mV absolute rating). |
| 2 | COMP | output | Compensation pin where error amplifier output appears; frequency and loop compensation RC network connected to this pin for control loop stabilization. |
| 3 | FB | input | Feedback pin where divided output voltage is applied; must be adjusted to 1.26V nominal using external resistor divider for voltage regulation. |
| 4 | AGND | power_in | Analog ground pin. |
| 5 | PGND | power_in | Power ground pin. |
| 6 | DR | output | Drive pin of the IC; external low-side N-Channel MOSFET gate must be connected to this pin with voltage swing limited to ≤8V absolute maximum. |
| 7 | FA/SYNC/SD | input | Frequency adjust, synchronization, and shutdown pin; external resistor to ground sets switching frequency from 100kHz to 1MHz, external clock input synchronizes operation, or high signal (≥30µs) enables shutdown mode with <10µA supply current. |
| 8 | VIN | power_in | Power supply input pin for converter operation over supply voltage range 2.97V to 40V. |
