The LM2576D2T-ADJG from onsemi is a classic, easy-to-use step-down switching regulator. It accepts a wide input voltage from 7V to 40V and provides an adjustable output from 1.23V to 37V, with a guaranteed 3A load current. The fixed 52kHz switching frequency simplifies design and filtering. Its TO-263 (D2PAK) package offers excellent thermal performance, making it a reliable choice for industrial and automotive power supplies.
- High Output Current (3A): Suitable for powering motors, actuators, and multiple digital loads.
- Wide Input Range (7V-40V): Works with 12V, 24V, and unregulated supplies.
- Simple Fixed-Frequency Design (52kHz): Reduces external component count and simplifies EMI compliance.
- Adjustable Output (1.23V-37V): Flexible for various voltage requirements.
Simple High-Current Power Supplies
The LM2576D2T-ADJG provides a simple, robust solution for generating 3.3V, 5V, or 12V from a 7V-40V input. Its 3A output is ideal for powering motors, relays, and high-power LEDs.
Automotive Aftermarket Electronics
In 12V vehicles, this converter steps down to 5V for dashcams, GPS trackers, and USB chargers. The 40V input rating handles voltage spikes from alternator load changes.
Industrial Control Panels
Convert 24V industrial supplies to 5V for PLCs, HMI displays, and sensor interfaces. The 52kHz fixed frequency simplifies EMI filtering and design.
Battery Chargers
Use as a constant-voltage source for charging 12V lead-acid or Li-ion batteries from a higher-voltage solar panel or DC supply.
Distributed Power Systems
In systems with a 24V or 48V backplane, the LM2576D2T-ADJG provides a local 5V or 3.3V rail, reducing noise and voltage drop across long traces.
Test and Measurement Equipment
Power analog and digital circuits from a bench supply. The adjustable output (1.23V-37V) allows flexible prototyping.
