Key Document


This is a dual, interleaved buck converter reference design, which covers an input voltage range of 17.0 V to 60.0 V. The output voltage is 12.0 V with a maximum load current of 15.0 A. The design has been space optimized and supports an average load current of 8.0 A.

  • High efficiency for low power dissipation in space constrained applications
  • Incorporates dual phase architecture and 3x3 MOSFETs for a small footprint
  • Very good load transient behavior resulting in small output voltage deviation
  • Tight output voltage regulation over a wide load current range
