LM2854MHX-500/NOPB TI Power Management IC | 16-HTSSOP | 500kHz, 4A Step-Down

Product Overview

The LM2854MHX-500/NOPB is a high-performance, 4A step-down (buck) regulator from Texas Instruments, designed for efficient power conversion in space-constrained applications. Housed in a 16-pin HTSSOP package with an exposed pad for enhanced thermal performance, this device operates at a fixed 500kHz switching frequency, enabling small external components while maintaining high efficiency. It integrates a low RDS(on) N-channel MOSFET and supports input voltages from 2.95V to 5.5V, making it ideal for point-of-load regulation in low-voltage systems.
