LM2642MTCX TI Dual Synchronous Buck Controller | 28-TSSOP | 5.5V-28V Input

Product Overview

The LM2642MTCX is a dual synchronous buck controller from Texas Instruments, designed for high-efficiency power conversion in a compact 28-TSSOP package. It integrates two independent PWM controllers with adaptive voltage positioning, enabling precise regulation for low-voltage, high-current applications. The device operates from an input voltage range of 5.5V to 28V and provides adjustable output voltages down to 0.6V. With a switching frequency programmable up to 1MHz, the LM2642MTCX minimizes external component size while maintaining excellent transient response.
