Description

This design has inductor over converter to achieve 30 A conversion in 1" by 0.6" (2.5 cm by 1.5 cm) footprint. The DCAP control of the controller provides a high speed control loop which is needed for applications with large rapidly varying loads, such as microprocessors. A high speed dynamic load is also included to verify this capability.

 

Features
  • Fully synchronous controller for lowest losses
  • DCAP2 control for excellent step load response
  • Compact design with inductor over controller
  • Thermal performance well documented both with & without fan
  • On board high speed dynamic test load to verify dynamic performance
  • Schematic, BOM, layout and Test Report focusing on thermal performance & load dynamics
