LM2641MTCX-ADJ/NOPB TI Dual Step-Down Controller | 28-TSSOP | 2.5V-5.5V Input, Adjustable Output

Product Overview

The LM2641MTCX-ADJ/NOPB is a dual-channel step-down (buck) switching controller from Texas Instruments, designed for high-efficiency power conversion in space-constrained applications. Housed in a 28-pin TSSOP package, this device operates from an input voltage range of 2.5V to 5.5V and provides two independent adjustable output voltages. With a switching frequency up to 1MHz, it enables compact power supply designs. The controller features current-mode control for excellent line and load regulation, and includes built-in protection features such as overcurrent and thermal shutdown.
