Texas Instruments LM5149
LM5149 80-V, Synchronous, Buck, DC/DC Controller with Ultra-Low IQ and Integrated Active EMI Filter
Overview
| Topology | Buck Converter |
| Input voltage | 12.5-72 V |
| Output 1 | 12 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 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
Typical applications
- Test and measurement
- Industrial transport
- Building automation
- Wireless infrastucture
