The National Semiconductor SIMPLE SWITCHER® LM2676LD-3-3 is a 3A, 3.3V fixed output voltage buck switching regulator in a 14-VSON (6x5) package. This device features a high switching frequency of 260kHz, enabling smaller component sizes and efficient power conversion. Designed for step-down applications, it offers a single positive fixed output voltage and requires no external synchronous rectifier. With an input voltage range of 8V to 40V and an output current capability of 3A, the LM2676LD-3-3 is suitable for demanding power supply designs in industrial control, medical equipment, and telecommunications infrastructure. The exposed pad on the 14-VDFN package enhances thermal performance. This component operates across a wide temperature range of -40°C to 125°C (TJ).
