Description

The PMP11220 reference design is a high efficiency, high power density, PMBus synchronous buck converter design for programming, and margining the power supply including output voltage.  With a nominal input of 24V meant for industrial bus applications, this design allows for programmable output voltages and minimal power loss, all in a small board space. DCAP2 control mode requires no loop compensation, enabling ease of design, while offering ultra-fast load transient response and use with all MLCC output caps.

Features
  • 94% Efficiency
  • Adjustable switching frequency and output voltage via PMBus
  • High Power Density
  • Minimal overshoot on switch node while maintaining high efficiency
  • This circuit design is tested and includes a full test report, schematic, and gerber files
  • Ultra-stable design: >75degrees of Phase Margin
