Description

This converter delivers -36V with 1.5Amax out of an input voltage range of 32V to 40V. Another focus is loop compensation for Cuk topology.

Features
  • Very low input and output ripple voltage due to LC filter in both directions
  • Well suited for studying the topology
  • Inverts positive input to negative output
