Overview

The LM25149-Q1EVM-2100 high-density evaluation module (EVM) is designed to showcase the performance of the LM25149-Q1 high-performance, automotive synchronous buck DC/DC buck controller. It operates over a wide input voltage range of 5.5 V to 36 V to deliver a fixed 5-V output with better than 1% setpoint accuracy and up to 8-A output current. The LM25149-Q1 offers advanced EMI performance and ultra-low IQ. Regulator features during fault conditions include: undervoltage lockout, internal soft-start, hiccup-mode overcurrent protection and thermal shutdown. Open-drain PGOOD indicator and SYNC IN / SYNC OUT features are also provided.

Features
  • 5.5-V to 36-V input voltage range
  • 5-V output voltage with 1% setpoint accuracy
  • Rated for 8 A of load current
  • Ultra-low IQ
  • Dual-random spread spectum and active EMI filtering for advance EMI mitigation
  • Fully assembled, tested and proven PCB layout with small footprint
