LM5008AMMX

Texas Instruments · DC-DC Converters · VSSOP-8-0.65mm

LM5008AMMX 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 power output connecting to output inductor, re-circulating diode, and bootstrap capacitor.
2 BST input Bootstrap capacitor input pin requiring 0.01-µF ceramic capacitor charged from VCC through internal diode during off-time.
3 RCL input Current limit off-time set pin with external resistor to RTN, preset to 35 µs when FB = 0 V.
4 RTN power_in Ground pin for entire circuit.
5 FB input Feedback input compared to 2.5 V internal reference in regulation comparator.
6 RT/SD input On-time set pin with external resistor to VIN with minimum 400 ns recommended on-time at maximum VIN, enables remote shutdown.
7 VCC power_out Regulated 9 mA current-limited power output for gate drive requiring 0.47-µF local decoupling capacitor.
8 VIN power_in Input voltage pin with operating range from 6 V to 95 V.
