LM2599S-ADJ/NOPB TI Switching Regulator | TO-263 (DDPAK-7) | 150kHz, 3A

Product Overview

The LM2599S-ADJ/NOPB is a high-efficiency, adjustable output voltage step-down (buck) switching regulator from Texas Instruments. It is part of the SIMPLE SWITCHER® series, designed to simplify power supply design with minimal external components. The device operates at a fixed switching frequency of 150 kHz, allowing for small filter components. It delivers up to 3A of continuous output current with excellent line and load regulation. The adjustable output voltage can be set from 1.2V to 37V using external resistors. The TO-263 (DDPAK-7) package provides excellent thermal performance for demanding applications.
