High Density Efficient Solution for Main Aux as well as Back up Aux Power in Drones


Design files


PMP10650 is a high power density 40W Buck Converter design optimized for Wide Vin Drone Design using the LM3150 controller IC (Used for Drone’s Backup Power) and LM53603. The design accepts an input voltage of 7Vin to 36Vin and provides the outputs of 5V@5A for Drone’s Backup power and 5V@3A for Drone’s manpower. It features a small size and is an inexpensive and more efficient solution.

  • Wide Vin Synchronous Buck Converter Design for both outputs
  • High Power Density
  • Efficiency 95%(LM3150) at 12V Input
  • Programmable Switching frequency (LM3150)-1MHz, External frequency synchronization in LM53603
  • COT Architecture in LM3150 allows Fast transient response
