LM26420YSQ/NOPB TI Dual Buck Regulator | 16-WQFN (4x4) | 2A Output, 2.95-5.5V Input

Product Overview

The LM26420YSQ/NOPB is a high-performance dual step-down (buck) switching regulator from Texas Instruments, designed for space-constrained applications. Housed in a compact 16-pin WQFN (4x4 mm) package, it delivers up to 2A per output with excellent efficiency. The device operates from an input voltage range of 2.95V to 5.5V, making it ideal for low-voltage systems powered by 3.3V or 5V rails. With integrated MOSFETs and a fixed 550 kHz switching frequency, the LM26420 minimizes external component count while providing stable output voltages as low as 0.8V.
