LM5008MMX from Texas Instruments, in a VSSOP-8-0.65mm. 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 | SW | output | Switching node connecting to output inductor, recirculating diode, and bootstrap capacitor. |
| 2 | BST | passive | Bootstrap capacitor input pin requiring external 0.01-µF ceramic capacitor between BST and SW, charged from VCC through internal diode. |
| 3 | RCL | input | Current limit OFF-time set pin where external resistor between this pin and RTN determines off-time when current limit is detected. |
| 4 | RTN | power_in | Ground pin providing ground reference for entire circuit. |
| 5 | FB | input | Feedback input pin connected to inverting input of internal regulation comparator with 2.5-V regulation threshold. |
| 6 | RON/SD | input | On-time set pin where external resistor between this pin and VIN determines switch on-time with minimum 400 ns at maximum input voltage; usable for remote shutdown. |
| 7 | VCC | power_out | Regulated 7-V output from internal high-voltage series pass regulator providing gate drive power for internal buck switch. |
| 8 | VIN | power_in | Input voltage pin with recommended operating range of 9.5 V to 95 V. |
