PMP30603 Reference Design

Texas Instruments

-60 V inverting buck-boost reference design

Description

This tiny reference design delivers -60-V output voltage from an input voltage around 5 V typically generated by an automotive pre regulator. The controller in that circuit is LM5161-Q1 providing two internal MOSFETs. Overall: this converter is used as auxiliary supply for LIDAR applications. 

Features
  • Capability to drive up to 40-mA peak for pulsed applicationsTemperature rise less than +30K at full loadLoad regulation 30 mV means only 0.05% output voltage deviationNo switch node ringing results in low radiated emissionsOutput voltage ripple only around 100 mVpp to supply sensitive load
Applications
  • Mechanically scanning LIDAR
