LM2678SD-ADJ Description

Short technical summary and product information.

The Texas Instruments LM2678SD-ADJ is a versatile 5A SIMPLE SWITCHER® buck converter designed for step-down voltage regulation. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage from 1.23V to 37V.

 

This device utilizes voltage mode control and operates at a fixed internal oscillator frequency of 260kHz. It boasts high efficiency, up to 92%, and features a 120mΩ DMOS output switch. The LM2678SD-ADJ offers ±2% maximum output tolerance over full line and load conditions and a low standby current of 50µA when switched off.

 

Packaged in a 14-VSON (5x6) surface-mount package, this component is suitable for various power management applications. Its operating junction temperature range is -40°C to 125°C, making it robust for demanding environments. The design is simplified by using off-the-shelf external components.
