Input voltage4.5-65 V
Switching frequency4.5 kHz
Output 115 V / 1.5 A
IC revisionA

Description

The LM5180EVM-DUAL evaluation module (EVM) is designed to showcase the performance of the LM5180 PSR flyback converter with wide input voltage range. The design is packaged in a miniature footprint with low component count. It operates over a wide input voltage range of 10 V to 65 V to deliver a 15-V and -7.7-V outputs at currents up to 200 mA. Operating without an auxilary winding or opto-coupler, the LM5180 provides very tight output voltage regulation, better than 1%. The LM5180 offers a full suite of protection features to ensure protection of the regulator during fault conditions. These include undervoltage lockout to ensure proper operation duing voltage-sag conditions, programmable soft-start to reduce inrsuh current, hiccup-mode overcurrent protection and thermal shutdown. Precision enable and output voltage thermal compensation features are also provided.

Features

10-V to 65-V input voltage range15-V and -7.7-V output voltagesRated for up to 200 mA of load currentResistor divider to EN/UVLO to faciltate programmable input voltage UVLOFully assembled, tested and proven PCB layout with small footprint

Typical applications

  • Isolated bias power rails
  • Automotive body electronics
  • Automotive power train systems
