LM2599S-12/NOPB TI DC-DC Converter | TO-263 (DDPAK-7) | 12V Fixed Output, 150kHz

Product Overview

The LM2599S-12/NOPB from Texas Instruments is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. It is capable of driving a 3A load with excellent line and load regulation. This device is available in a fixed output voltage of 12V and operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. The LM2599S-12/NOPB is offered in a TO-263 (DDPAK-7) package, which is suitable for surface mount applications. It features a wide input voltage range from 4.5V to 40V, making it ideal for a variety of power conversion applications.
