The LM2575HVS-ADJ is a robust, simple step-down (Buck) DC-DC converter from UMW, designed for high-voltage applications. It accepts a wide input voltage up to 57V and provides an adjustable output from 1.2V, delivering up to 2A of load current. With a fixed 150kHz switching frequency, it requires only a minimal number of external components. Its high input voltage rating and TO-263 package make it a reliable choice for industrial, telecom, and automotive power supplies.
- High Input Voltage: Handles up to 57V, making it suitable for 48V and 24V systems with ample voltage margin.
- Simple Design: Requires minimal external components due to its fixed 150kHz switching frequency and internal compensation.
- High Output Current: Delivers up to 2A, sufficient for a wide range of loads.
- Proven Topology: Based on the industry-standard LM2575 architecture, ensuring reliability and ease of use.
High-Voltage Industrial Power Supplies
The 57V input capability makes it perfect for industrial control systems, motor drives, and factory automation equipment operating from 48V or 36V rails, providing a robust and simple step-down solution.
Telecom and Networking Equipment
Ideal for converting 48V telecom backplane voltages down to 5V or 3.3V logic rails for routers, switches, and base stations, offering a reliable and cost-effective power stage.
Automotive Battery Systems
In 24V automotive systems, this converter can efficiently step down to power sensors, ECUs, and infotainment systems, handling voltage transients and load variations with ease.
Renewable Energy and Battery Charging
Can be used in solar charge controllers or battery management systems to step down higher panel or battery voltages to charge lower voltage batteries or power monitoring circuits.
Distributed Power Architectures
As a simple, high-voltage POL converter, it can generate auxiliary rails from a high-voltage main bus, simplifying the overall power supply design in various systems.
