LM5009AMMX

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

LM5009AMMX 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 switching node connected to the output inductor, recirculating diode, and bootstrap capacitor.
2 BST input Boost pin (bootstrap capacitor input) requiring an external capacitor between BST and SW, with a 0.01-µF ceramic capacitor recommended.
3 RCL input Current limit OFF-time set pin; a resistor between RCL and RTN sets the OFF time when current limit is detected, preset to 35 µs if FB = 0 V.
4 RTN power_in Ground pin providing ground for the entire circuit.
5 FB input Feedback input from the regulated output to the inverting input of the internal regulation comparator, with a regulation threshold of 2.5 V.
6 RT/SD input On-time set pin; a resistor between RT/SD and VIN sets the switch on time, with a minimum recommended on time of 400 ns at maximum input voltage, and the pin is also used for remote shutdown.
7 VCC power_out Output of the internal high-voltage series pass regulator providing gate drive power, current limited to 9 mA, requiring a local 0.47-µF decoupling capacitor.
8 VIN power_in Input voltage pin with an operating input range of 6 V to 95 V.

CAD (KiCad official)

  • Symbol: LM5009AMMX
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8-0.65mm (KiCad packages3D, STEP)
  • 3D model files: lm5009ammx-etched.step / lm5009ammx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm5009ammx.step / lm5009ammx.glb are the bare package body.
