The Texas Instruments LM2576HVT-ADJ/LF03 is a versatile adjustable step-down switching regulator. It accepts a wide input voltage from 4V to 60V and provides an adjustable output from 1.23V to 57V, with a load current capability of up to 3A. Operating at a fixed 52kHz switching frequency, it offers a good balance between efficiency and external component size. The TO-220-5 package with formed leads is designed for through-hole mounting and excellent thermal performance. This regulator is well-suited for a wide range of applications, from industrial power supplies to automotive electronics, where design flexibility and reliability are paramount.
- Adjustable Output (1.23V-57V): One part covers multiple voltage rails, reducing inventory and design time.
- Wide Input Range (4V-60V): Robust operation in automotive and industrial environments with voltage spikes.
- 3A Output Current: Powers high-current loads like motors, solenoids, and multiple ICs.
- 52kHz Fixed Frequency: Predictable EMI spectrum simplifies filtering and compliance testing.
Adjustable Power Supplies for Test Equipment
The 1.23V to 57V adjustable output allows designers to create versatile bench power supplies with a single converter, covering logic, analog, and power stages.
Automotive Sensor and ECU Power
With a 60V input rating, it safely regulates battery voltage down to custom levels (e.g., 3.3V, 5V, 12V) for ECUs and sensors, even during cranking transients.
Industrial Process Control Loops
Provides precise adjustable voltages for 4-20mA transmitters, PLCs, and field instruments, ensuring stable operation in noisy factory environments.
Battery Charging Circuits
The adjustable output enables constant-voltage charging profiles for lead-acid or lithium batteries, with 3A capability for moderate charging rates.
Networking Equipment Power Rails
Flexible output voltage simplifies generation of multiple rails (e.g., 1.8V, 2.5V, 3.3V) from a single 48V telecom bus, reducing component count.
Prototyping and Development Boards
Ideal for evaluation boards where engineers need to test different voltage levels quickly, thanks to its wide adjustment range and high current.
