Design files

Overview

This circuit reference design is realized in Cuk Topology. The output voltage is -12V / -15V. The output current of 200mA is possible over an input voltage range of 10V to 60V  (even with a low input voltage of 6V 140mA output current is possible).  The perfect switching behavior of the circuit results in lowest radiated emissions.

Features
  • Cost effective (LM5001, TLV271)
  • Suitable for audio
  • Despite Cuk topology, excellent dynamic behavior
  • Lowest ripple at input and output
  • Transient response on a 50% load step is only 1%
  • The circuit reference design is built and tested
