LM2599S-5.0/NOPB TI Step-Down Regulator | TO-263 | 5V Output, 150kHz

Product Overview

The LM2599S-5.0/NOPB is a high-efficiency step-down (buck) switching voltage regulator from Texas Instruments. It provides a fixed 5V output with a load current capability of up to 3A. This device operates at a switching frequency of 150 kHz, allowing for small external components. The LM2599 series is a monolithic integrated circuit that includes a 150 kHz fixed-frequency internal oscillator, a temperature-compensated reference, a high-gain error amplifier, current limit comparator, and a high-current output switch. The LM2599S-5.0/NOPB is available in the TO-263 (DDPAK-7) package, which offers excellent thermal performance for high-power applications.
