Tiny -60-V cuk reference design for automotive applications

Design files

Overview

This tiny reference design delivers -60-V output voltage from an input voltage around 5 V. It is typically generated by an automotive pre regulator. The LM5001-Q1 is the controller, TLV271-Q1 converts the negative output voltage to be suitable for positive feedback (FB) input of the LM5001.  In general, this converter is used as auxiliary supply for LIDAR applications.

Features
  • Peak efficiency 75% despite large duty cycle, total power losses < 500 mW
  • Fine thermal behavior, temperature rise less than +20K at full load
  • Load regulation less than 30 mV means less than 0.05%
  • Output ripple around 200mVpp
  • Low reflected ripple (= conducted emissions) by Cuk topology (= inverting SEPIC)
