Texas Instruments LM5164 | Demoboard LM5164-Q1EVM-041
Synchronous step-down converter evaluation module
Overview
| Topology | Buck Converter |
| Input voltage | 15-100 V |
| Output 1 | 12 V / 1 A |
| IC revision | A |
Description
The LM5164-Q1 synchronous buck converter is designed to regulate over a wide input voltage range, minimizing the need for external surge suppression components. A minimum controllable on-time of 50 ns facilitates large step-down conversion ratios, enabling the direct step-down from a 48-V nominal input to low-voltage rails for reduced system complexity and solution cost. The LM5164-Q1 operates during input voltage dips as low as 6 V, at nearly 100% duty cycle if needed, making it an excellent choice for high-performance 48-V battery automotive applications and MHEV/EV systems.
Features
- Inegrated Synchronous Rectification
- Low Operating Quiescent Current
- High Efficiency at Light Loads
- Short Minimum On-time
Typical applications
- High Cell Count Battery Packs for E-Bikes, E-Scooters and Drones
- Automotive 48-V Mild Hybrid ECU Bias Supplies, Automotive DC/DC Converter, PTC Heater, HVAC Compressors, Automotive and Industrial Battery-Powered Equipment
- General-Purpose Bias Supplies
