Texas Instruments SIMPLE SWITCHER® LM2679SX-3-3-NOPB is a high-efficiency, easy-to-use, monolithic synchronous step-down voltage regulator. This device delivers 3.3V fixed output with a maximum output current of 5A. Designed for robust performance, it operates with an input voltage range of 8V to 40V and features an integrated switch with a typical on-resistance of 100mO, eliminating the need for external Schottky diodes. The internal oscillator is fixed at 260kHz, simplifying design and ensuring predictable performance. The TO-263-8, D2PAK package facilitates efficient heat dissipation for demanding applications. This component is suitable for power supply designs in industrial automation, consumer electronics, and telecommunications sectors.
