Texas Instruments LM65680-Q1 | Demoboard LM65680-Q1EVM
Automotive 65V, 8A synchronous buck converter optimized for low-EMI
Overview
| Topology | Buck Converter |
| Input voltage | 6-70 V |
| Output 1 | 5 V / 8 A |
| IC revision | A |
Description
The LM65680-Q1 evaluation module (EVM) is a synchronous buck DC/DC regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 6V to 70V, which offers outsized voltage rating and operating margin to withstand supply-rail voltage transients while providing a regulated output of 5V. The output voltage has better than 1% setpoint accuracy and is adjusted by modifying the feedback resistor values, permitting the user to customize the output voltage as needed.
Features
Wide input voltage operating range of 6V to 70V5V output voltage with 1% setpoint accuracyRated for 8A of load currentLow minimum on time (40ns maximum)Optional dual-random spread spectum and slew-rate control for EMI mitigationFully assembled and tested PCB layout with small footprint
