The Texas Instruments LM2678T-5.0 is a 5A SIMPLE SWITCHER buck converter designed for step-down voltage regulation. It features a wide input voltage range from 8V to 40V, making it suitable for various power supply applications. This device offers a fixed 5V output voltage with a maximum output current of 5A.
Key electrical characteristics include a switching frequency of 260kHz and a maximum efficiency of up to 92%. The LM2678T-5.0 includes features such as over-current protection and a standby current of only 50µA when switched off. The output voltage tolerance is ±2% over the full line and load conditions.
Packaged in a TO-220-7 format with formed leads, this component is designed for through-hole mounting. Its operating temperature range is -40°C to 125°C (TJ). The design is simplified by using off-the-shelf external components, and it incorporates a 120mΩ DMOS output switch.
This buck converter is ideal for applications requiring efficient and reliable power conversion within its specified voltage and current limits. Its robust design and wide input range contribute to its versatility in industrial and commercial power systems.
