LM5008MMX

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

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.
