The ON Semiconductor LM2575D2T-ADJ is a versatile adjustable DC-DC switching regulator designed for step-down (buck) conversion. It accepts an unregulated DC input voltage between 8.0 V and 40 V, providing flexibility for various power supply designs.
Key electrical characteristics include a typical switch saturation voltage of 1.0 V and a reference voltage of 1.23 V. The ON/OFF pin allows for logic-level shutdown, reducing input supply current to approximately 80 mA in standby mode, with a typical threshold voltage of 1.4 V.
Proper PCB layout is crucial for optimal performance, minimizing inductance and ground loops to reduce EMI. Single-point grounding or ground plane construction is recommended. The feedback loop wiring should be kept short, with programming resistors located near the regulator for the adjustable version.
This component is suitable for a wide range of power management applications where adjustable output voltage and efficient step-down conversion are required.
