Product Introduction

Overview

The LM2592HVS-3.3/NOPB is a monolithic integrated circuit from Texas Instruments, designed as a high-efficiency step-down (buck) switching regulator. This device is part of the SIMPLE SWITCHER series and is capable of driving a 2-A load with excellent line and load regulation. It is available in fixed output voltages, including 3.3 V, and an adjustable output version. The LM2592HV series is known for its simplicity, requiring a minimum number of external components, and includes internal frequency compensation and a fixed-frequency oscillator operating at 150 kHz.
