Product details

Description

The LM5149 is a 80-V, ultra-low IQ synchronous buck DC/DC controller for high-current, single-output applications.

The controller uses a peak current-mode control architecture for easy loop compensation, fast transient response, and excellent load and line regulation.

Features

Functional Safety-Capable.
Documentation available to aid functional safety system design.
Two integrated EMI mitigation mechanisms.
Active EMI Filter for enhanced EMI performance at lower frequencies.
Selectable dual random spread spectrum (DRSS) for enhanced EMI performance across low and high-frequency bands.
EMI reduced by an average of 25 dBµV.
Reduces the external differential-mode input filter size by 50% and lowers systems c.
