Texas Instruments LM25180-Q1 | Demoboard LM5180EVM-DUAL
Automotive 42-VIN no-opto flyback converter with 65-V, 1.5-A integrated MOSFET
Overview
| Topology | Flyback Converter |
| Input voltage | 4.5-65 V |
| Switching frequency | 4.5 kHz |
| Output 1 | 15 V / 1.5 A |
| IC revision | A |
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
