The LM2678SX-3.3/NOPB from Texas Instruments is a monolithic, integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving loads up to 5A and offers excellent line and load regulation characteristics. This regulator achieves high efficiency, up to 92%, through the use of a low ON-resistance DMOS power switch.
Key electrical specifications include a wide input voltage range of 8V to 40V and a fixed 3.3V output voltage. It operates with a fixed 260kHz internal oscillator frequency. The device also features a low standby current of 50µA when switched off and maintains an output tolerance of ±2% over full line and load conditions.
The LM2678SX-3.3/NOPB is housed in a TO-263 package with 7 pins. It has an operating junction temperature range of -40°C to 125°C. The regulator is designed for ease of use with off-the-shelf external components, simplifying the design process for power management applications.
