The onsemi LM2576TV-ADJG is a versatile buck DC-DC converter designed for high-voltage step-down applications. It accepts a wide input voltage from 7V to 40V and provides an adjustable output from 1.23V to 37V, delivering up to 3A of continuous current. Operating at a fixed 52kHz switching frequency, it offers a good balance between efficiency and component size. Housed in a robust TO-220-5 package, this converter is well-suited for automotive, industrial, and distributed power systems requiring reliable and simple power conversion.
- Wide Input Voltage Range: Handles 7V to 40V, making it suitable for automotive and industrial 12V/24V systems.
- High Output Current: Delivers up to 3A, sufficient for powering microcontrollers, sensors, and small motors.
- Simple External Circuitry: Requires minimal external components, simplifying design and reducing BOM cost.
- Robust Package: The TO-220 package offers excellent thermal performance for high-power applications.
Automotive Power Systems
The wide 7V to 40V input range makes the LM2576TV-ADJG ideal for automotive environments, stepping down 12V or 24V battery voltages to regulated 5V or 3.3V for ECUs, sensors, and infotainment systems, withstanding load-dump transients.
Industrial Control Equipment
In industrial settings with 24V DC rails, this buck converter provides a stable lower voltage for microcontrollers, PLCs, and motor control logic, offering robust performance and thermal protection in harsh environments.
Distributed Power Architectures
Use it as an intermediate bus converter to step down a high-voltage backplane (e.g., 48V) to a local 12V or 5V rail for point-of-load regulators, simplifying power distribution in networking and telecom equipment.
Battery Charging Circuits
Configure the adjustable output to create a constant-voltage/constant-current charger for lead-acid or Li-Ion batteries from a higher voltage solar panel or AC adapter, ensuring safe and efficient charging.
Test and Measurement Instruments
Provide a clean, regulated supply for precision analog circuits in bench-top instruments. The simple design and low noise output help maintain measurement accuracy.
White Goods and Appliances
Power control boards in washing machines, refrigerators, and air conditioners from the main DC bus, reducing heat dissipation compared to linear regulators and improving overall energy efficiency.
