The LM2677SD-5.0 from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications, capable of driving up to 5A loads. It features a fixed 5V output voltage and a wide input voltage range of 8V to 40V.
This regulator boasts high efficiency, up to 92%, due to its low ON-resistance DMOS output switch. The internal oscillator operates at a fixed frequency of 260kHz, but external synchronization is also supported between 280kHz and 400kHz, allowing for smaller external components and precise control of the output ripple frequency.
Key features include ±2% maximum output tolerance over full line and load conditions, 50μA standby current when switched off, and a -40°C to 125°C operating junction temperature range. The LM2677SD-5.0 is available in a 14-VSON (5x6) package suitable for surface mounting.
This device simplifies design with a minimum number of external components and includes built-in thermal shutdown and current limiting for protection.
