DC Switching Voltage Regulators

LM5001MAX Description

The LM5001MAX from Texas Instruments is a versatile, high-voltage DC switching voltage regulator designed for demanding power management applications. This obsolete but robust IC supports an adjustable output configuration with a wide input voltage range (3.1V to 75V), making it suitable for systems requiring isolation or high-voltage step-up/down conversion. The device delivers up to 800mA (switch current) and operates at a switching frequency range of 50kHz to 1.5MHz, enabling flexibility in design trade-offs between efficiency and component size. Its positive, isolation-capable output and support for multiple topologies (Boost, Flyback, Forward Converter, SEPIC) make it a adaptable solution for diverse power architectures.

LM5001MAX Features

• Wide Input Range (3.1V–75V): Ideal for automotive, industrial, and telecom applications with fluctuating input voltages.
• Adjustable Output (3.1V–76V): Precision voltage regulation for custom power requirements.
• Multi-Topology Support: Compatible with Boost, Flyback, Forward, and SEPIC configurations.
• High Switching Frequency (1.5MHz max): Enables compact designs with smaller passive components.
• Non-Synchronous Rectification: Simplifies design while maintaining efficiency.
• Surface-Mount (SOIC-8) Packaging: Suitable for space-constrained PCB layouts.
• REACH Unaffected & MSL 1: Compliant with environmental regulations and suitable for extended storage.

LM5001MAX Applications

The LM5001MAX excels in:

• Industrial Power Supplies: Isolated converters for PLCs, motor drives, and sensors.
• Automotive Systems: Voltage regulation in infotainment, lighting, and battery management.
• Telecom/Networking: DC-DC conversion for base stations and PoE (Power over Ethernet) equipment.
• Renewable Energy: MPPT controllers and auxiliary power in solar/wind systems.
• LED Drivers: High-voltage constant-current supplies for lighting applications.

Conclusion of LM5001MAX

The LM5001MAX is a highly flexible, high-voltage switching regulator tailored for engineers needing wide input range, multi-topology support, and isolation capability. While marked obsolete, its performance in industrial, automotive, and telecom applications remains relevant for legacy designs or specific high-voltage requirements. Its compact SOIC-8 package and adjustable output make it a pragmatic choice for systems demanding reliability under variable input conditions. For modern alternatives, consider Texas Instruments' newer offerings with enhanced efficiency and synchronous rectification.
