Texas Instruments LM5149
80-V synchronous buck DC/DC controller with ultra-low IQ and integrated active EMI filter
Overview
| Topology | Buck Converter |
| Input voltage | 5.5-36 V |
| Output 1 | 5 V / 8 A |
| IC revision | A |
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. The LM5149 can be set up in interleaved dual-phase mode with accurate current sharing for high-current applications. The device can operate with VIN as low as 3.5 V, at nearly 100% duty cycle if needed.
Features
- Functional Safety-Capable– Documentation available to aid functional safetysystem design
- Two integrated EMI mitigation mechanisms– Active EMI Filter for enhanced EMIperformance at lower frequencies– Selectable dual random spread spectrum(DRSS) for enhanced EMI performance across
Typical applications
- Test and measurement
- Building automation
- Industrial transport
- Wireless infrastucture
