Texas Instruments LM2679T-3-3 is a SIMPLE SWITCHER® buck switching regulator designed for efficient step-down voltage conversion. This device offers a fixed 3.3V output voltage and a substantial 5A continuous output current capability. The integrated design simplifies power supply circuitry, requiring minimal external components. Operating at a 260kHz switching frequency, it achieves a compact solution size. The TO-220-7 package with formed leads ensures robust through-hole mounting for demanding applications. With an input voltage range from 8V to 40V and an operating temperature range of -40°C to 125°C, the LM2679T-3-3 is suitable for industrial, automotive, and consumer electronics power management. Its non-synchronous buck topology provides a reliable and cost-effective solution for power supply designs.
