The LM2596S-3.3 with DC-DC Converters TO-263 RoHS manufactured by Youtai is a monolithic step-down switching regulator with an adjustable output voltage of 3.3V. It has a high switching frequency of 150 kHz, allowing it to deliver up to 3 A continuous output current. It also features a low quiescent current of 18 µA, which enables lower system power consumption. The device is packaged in a TO-263 RoHS package which makes it suitable for surface mount manufacturing. It also has built-in protection features, including overcurrent protection, short-circuit protection, thermal shutdown protection, and a preventing bleed current function which eliminates excess inrush current when powering up the system. This device is ideal for applications which require efficient switching converters with wide input voltage ranges and adjustable output voltage settings.
