The Texas Instruments LM2678T-ADJ is a monolithic integrated circuit designed as a step-down (buck) switching regulator. Capable of driving loads up to 5A, it offers excellent line and load regulation characteristics. The device achieves high efficiency, up to 92%, through its low ON-resistance DMOS power switch.
Key electrical specifications include a wide input voltage range of 8V to 40V and a fixed switching frequency of 260kHz. The output voltage is adjustable from 1.2V to 37V, with a maximum output tolerance of ±2% over full line and load conditions. It also features a low standby current of 50µA when switched off.
This regulator is housed in a TO-220-7 package and supports through-hole mounting. The SIMPLE SWITCHER concept allows for a complete design using a minimum number of external components, simplifying the design process. Built-in thermal shutdown and current limiting provide protection.
