LM70880-Q1 Buck Converter Evaluation Module

Overview

TopologyBuck Converter
Input voltage8-72 V
Output 15 V / 8 A
IC revisionA

Description

The LM70880QEVM high-density evaluation module is designed to use a regulated or non-regulated high-voltage input rail ranging from 8V to 72V to produce a tightly regulated output voltage of 5V at load currents up to 8A. The LM70880-Q1 features high conversion efficiency, superior thermal performance and advanced EMI mitigation.

Features

  • 8V to 72V input voltage range
  • 5V output voltage with 1% setpoint accuracy
  • Rated for 8A of load current
  • Ultra-low IQ
  • Optional dual-random spread spectrum (DRSS) for EMI mitigation

Typical applications

  • Communications: WLAN, AAS and RRU
  • Industrial: motor drives (Servo/AC), factory automation, off-highway vehicles and eBikes
  • Automotive: ADAS, infotainment and cluster, Automotive HEV/EV powertrain systems, High-current automotive electronic systems
