The LM2575D2T-012 from On Semiconductor is a step-down (buck) switching regulator. It is designed for applications requiring a regulated DC voltage from a wider input range.
Key electrical characteristics include an input voltage range of 8.0 V to 40 V and a fixed 12 V output voltage. The internal switch has a typical saturation voltage of 1.0 V. The ON/OFF pin allows for logic-level shutdown, reducing input supply current to approximately 80 mA, with a typical threshold voltage of 1.4 V.
Proper PCB layout is crucial for switching regulators to minimize electromagnetic interference (EMI) and ensure stable operation. Recommendations include keeping high-current paths short, using single-point grounding or a ground plane, and minimizing the PCB area connected to the output switch pin. Sensitive feedback wiring should also be kept short.
This component is suitable for various power supply applications where efficient voltage conversion is needed. Its robust design and specified input voltage range make it a versatile choice for embedded systems and power management circuits.
