Product Overview

The 551011367-011/NOPB is an unpopulated bare board for LM2598. The LM2598 series of regulators are monolithic integrated circuits that provide all the active functions for a step down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. The LM2598 series operates at a switching frequency of 150kHz. The LM2598 series are available in a standard seven lead TO220 package with several different lead bend options and a seven lead DDPAK SMD package. This series of switching regulators is similar to the LM2595 series, with additional supervisory and performance features added.
