LM20123MH/NOPB TI Power Management IC | 16-HTSSOP | 3A, 1.5MHz Step-Down Regulator

Product Overview

The LM20123MH/NOPB is a high-performance, 3A step-down DC-DC converter from Texas Instruments, designed for point-of-load regulation in space-constrained applications. Housed in a 16-pin HTSSOP package, it integrates a high-side MOSFET and operates at a fixed 1.5MHz switching frequency, enabling small external components. With an input voltage range of 2.95V to 5.5V, it is ideal for low-voltage systems requiring high efficiency and fast transient response.
